Hot

I'm typesetting a cover letter using LaTeX, and at the top of the page, separated from the rest by a rule, is my name and contact information. In order to achieve this, I've put a box and a parbox, separated by /hfill, into another box. The parbox is raggedleft, but there is still a little bit of space between the edge of its text and the right margin, which to me looks unsightly: \documentclass{letter} \signature{Firstname Lastname} \begin{document} \begin{letter}{Recipient Address} \makebox[\linewidth]{% \makebox{\Huge{Firstname Lastname}}% \hfill \makebox{ \parbox{110pt}{ \raggedleft +1 (234) 567-8910 \\ emailaddress@gmail.com \\ Earth, probably } }} \smallskip\hrule height .4pt \normalsize \opening{Dear Recruiter,} Some paragraphs and stuff. \closing{So hire me.} \end{letter} \end{document} I've read the entries in the texdoc LaTeX2e manual for box and parbox, but there doesn't seem to be anything about the boxes themselves taking up extra space. I've read around sections of the manual that seem related, and looked around on the internet, but so far have come up with no solution. Does anyone know why that space is there, and how to remove it?

Question: In this post, how do we fix the code \pagestyle{plain} and \pagestyle{myotherheadings}? In my previous post, I wanted a page number in the upper left corner for even numbered pages and upper right corner for odd numbered pages? After printing the document, I realized the page numbers should be reversed: i.e., in the upper right corner for even numbered pages and the upper left corner for odd number pages. Moreover, I want the chapter titles in each page to be on the opposite same upper corners to the page numbers. Here is what I tried, when using the post, "Change page number position with \pagestyle{myheadings}" I have the following file tree for my \usepackage{report} document: - File Tree - chapters - appendix.tex - chapter02.tex - chapter03.tex - chapter04.tex - introduction.tex - abstract.tex - main.tex - mendeley.bib - references.bib - titlepage.tex Here is the following code in main.tex. (The rest of the files can be filled with lipsum.) \documentclass[11pt,twoside]{report} \usepackage{graphicx} \graphicspath{ {images/} } \usepackage{caption} \usepackage{subcaption} \usepackage{float} \usepackage[width=150mm,top=35mm,bottom=25mm,bindingoffset=6mm]{geometry} \usepackage{fancyhdr} \usepackage{setspace} \pagestyle{plain} \makeatletter \def\ps@myotherheadings{% \def\@evenfoot{\thepage\hfil}% -> page number then fill \def\@oddfoot{\hfil\thepage} % -> fill, then page number \def\@oddhead{{\slshape\rightmark}\hfil} % remove the page number \def\@evenhead{\hfil\slshape\leftmark}% \let\@mkboth\@gobbletwo \let\sectionmark\@gobble \let\subsectionmark\@gobble} \pagestyle{myotherheadings} \fancypagestyle{plain}{% \fancyhf{} \fancyfoot[R]{\thepage} \renewcommand{\headrulewidth}{0pt}} \usepackage{titlesec} \usepackage{biblatex} \addbibresource{references.bib} \title{Title} \author{Arbuja} \date{July 13th, 2026} \begin{document} \pagenumbering{roman} \input{titlepage} \input{abstract} \tableofcontents \listoffigures \doublespacing \chapter{Introduction} \pagenumbering{arabic} \markboth{Chapter 1: Introduction}{Chapter 1: Introduction} \input{chapters/introduction} \chapter{Asd} \markboth{Chapter 2: Asd}{Chapter 2: Asd} \input{chapters/chapter02} \chapter{Bsd} \markboth{Chapter 3: Bsd}{Chapter 3: Bsd} \input{chapters/chapter03} \chapter{Csd} \markboth{Chapter 4: Csd}{Chapter 4: Csd} \input{chapters/chapter04} \appendix \chapter{Dsd} \markboth{Appendix: Dsd}{Appendix: Dsd} \input{chapters/appendix} \singlespacing \printbibliography \end{document}

I came here from another question. After adopting the solution an answer, using zhnumber, titlesec, and ctex, I can create headings that employ Chinese (Traditional, but shouldn't matter here) numerals such as 壹、這是第壹章 instead of 1 這是第壹章 However, while this works for section-level headers in the body of the document, it is not reflected in the Table of Contents. Is there a way to fix this? For reference I use Overleaf, XeLaTeX, and the xeCJK package. MWE: \documentclass{article} \usepackage{xeCJK} \setCJKmainfont{Noto Sans CJK TC} \usepackage{titlesec} \usepackage{zhnumber} \titleformat{\section} {\Large\bfseries} {\zhnum[style={Financial,Traditional}]{section}、} {0pt} {} \titleformat{\subsection} {\large\bfseries} {\zhnum{subsection}、} {0pt} {} \renewcommand{\contentsname}{目錄} \begin{document} \tableofcontents \section{甲章} \subsection{甲節} \subsection{乙節} \section{乙章} \subsection{甲節} \subsection{乙節} \end{document}

Let's consider the following THREE examples: Example1. with newtx: \documentclass{article} \usepackage{newtx} % \usepackage{newtxtext} % \usepackage{newtxmath} \begin{document} ABCDE abcde 12345 $ABCDE abcde 12345$ \end{document} Both the number in text or math was turned "Times": Example2. with newtxtext: \documentclass{article} % \usepackage{newtx} \usepackage{newtxtext} % \usepackage{newtxmath} \begin{document} ABCDE abcde 12345 $ABCDE abcde 12345$ \end{document} Only the text was turned "Times", that was the expected behaviour. Example3. with newtxmath: \documentclass{article} % \usepackage{newtx} % \usepackage{newtxtext} \usepackage{newtxmath} \begin{document} ABCDE abcde 12345 $ABCDE abcde 12345$ \end{document} That was confusing for me, if and only if newtx was loaded, the numbers in math would be changed to "Times"-style, that was out of my expectation. My question is: Is the behaviour of newtxmath that didn't change the number in math that expected? How the numbers in math's font was decided? How could I know whether a package for example fourier-otf or xcharter-otf that change the numbers' font in math? Edited With cabohah's comment, the code works: \documentclass[a5paper]{article} \renewcommand*{\rmdefault}{minntx} \usepackage{newtxmath} \usepackage[no-math]{fontspec} \setmainfont{Latin Modern Roman} \begin{document} ABCDE abcde 12345 $ABCDE abcde 12345$ \end{document} However, since newtx-bundle was pdftex-friendly, the solution above loads the fontspec, that was unicode engine needed... I still wonder why newtxmath didn't take over numbers in math formula 😉

Latex is producing a blank page, which I want to remove, between the first \includepdf and \section{DC1459B}. I tried everything to try to remove that annoying blank page, to no avail. \chapter{Technical Datasheets} \label{chapter:appendixDatasheets} % ---------------------------------------------------------------------- \section{LTC3588-1} %\cite{ltc3588_1_datasheet} \label{section:ltc datasheet} \begin{figure}[!ht] \centering \begin{subfigure}[b]{0.49\textwidth} \centering \includegraphics[width=\textwidth, page=1]{Figures/ltc3588 datasheet.pdf} \caption*{} \label{fig:ltc3588_p1} \end{subfigure} \hfill \begin{subfigure}[b]{0.49\textwidth} \centering \includegraphics[width=\textwidth, page=2]{Figures/ltc3588 datasheet.pdf} \caption*{} \label{fig:ltc3588_p2} \end{subfigure} \caption*{} \label{fig:ltc3588_first2} \end{figure} \includepdf[pages={3-20}, nup = 2x2, landscape=false, scale=1, pagecommand={\thispagestyle{plain}}]{Figures/ltc3588 datasheet.pdf} \section{DC1459B} %\cite{dc1459b_user_guide} \begin{figure}[H] \centering \begin{subfigure}[b]{0.56\textwidth} \centering \includegraphics[width=\textwidth, page=1]{Figures/dc1459B.pdf} \caption*{} \label{fig:dc1459b_page1} \end{subfigure} \hfill \begin{subfigure}[b]{0.56\textwidth} \centering \includegraphics[width=\textwidth, page=2]{Figures/dc1459B.pdf} \caption*{} \label{fig:dc1459b_page2} \end{subfigure} \caption*{} \label{fig:dc1459b_page1_2} \end{figure} \includepdf[pages={3-6}, nup=2x2, landscape=false, scale=1, pagecommand={\thispagestyle{plain}}]{Figures/dc1459B.pdf} Also, I really have to include the first two pages as images using \includegraphics, not with \includepdf, otherwise it won't fit.

Question: In the following code, how do we place a page number in the upper left corner for even numbered pages and upper right corner for odd numbered pages? (In the current code, the page number is on the bottom center.) I have the following file tree for my \usepackage{report} document: - File Tree - chapters - appendix.tex - chapter02.tex - chapter03.tex - chapter04.tex - introduction.tex - abstract.tex - main.tex - mendeley.bib - references.bib - titlepage.tex I have the following code in main.tex. (The rest of the files can be filled with lipsum.) \documentclass[11pt,twoside]{report} \usepackage[utf8]{inputenc} \usepackage{graphicx} \graphicspath{ {images/} } \usepackage{caption} \usepackage{subcaption} \usepackage{float} \usepackage[width=150mm,top=35mm,bottom=25mm,bindingoffset=6mm]{geometry} \usepackage{fancyhdr} \usepackage{setspace} \pagestyle{plain} \fancyhf{} \fancyhead[R]{\thepage} \renewcommand{\headrulewidth}{0pt} \setlength{\headheight}{14pt} \usepackage{biblatex} \addbibresource{references.bib} \title{Title} \author{Arbuja} \date{July 13th, 2026} \begin{document} \pagenumbering{roman} \input{titlepage} \input{abstract} \tableofcontents \listoffigures \doublespacing \chapter{Introduction} \pagenumbering{arabic} \input{chapters/introduction} \chapter{Asd} \input{chapters/chapter02} \chapter{Bsd} \input{chapters/chapter03} \chapter{Csd} \input{chapters/chapter04} \appendix \chapter{Dsd} \input{chapters/appendix} \singlespacing \printbibliography \end{document} Note: There is plenty of additional code in the original version. If the code you give doesn't work with the rest of the code, see this document. (The only changes I want is for even numbered pages, the page number should be on the upper left corner and for odd numbered pages, the page number should be on upper right corner.)

In my document, I add label to sections, figures etc with the following \label{sec:a}. In an English document, when I want to refer to these label using the package cleverref (with \cref{sec:a}) and all works well. But if I change the document language to French, I get the following error Missing \endcsname inserted. <to be read again> The issue of the error is the colon : in the label, if I use sec-a instead of sec:a, the compilation works well.

I'm trying to make all the column into para alignment with equal columnsep, I've referred the answer from @egreg Cells of equal width using tabular which is somewhat match with my requirement and not sure how to fix para mode alignment, and the MWE is: \documentclass{book} \ExplSyntaxOn \newenvironment{ftabular}[2][c] { \lawrence_ftabular:nn { #1 } { #2 } } { \endtabular } \tl_new:N \l__lawrence_ftabular_header_tl \dim_new:N \l__lawrence_ftabular_maxwd_dim \box_new:N \l__lawrence_ftabular_item_box \cs_new_protected:Nn \lawrence_ftabular:nn { \tl_clear:N \l__lawrence_ftabular_header_tl \dim_zero:N \l__lawrence_ftabular_maxwd_dim \clist_map_inline:nn { #2 } { \hbox_set:Nn \l__lawrence_ftabular_item_box { ##1 } \dim_set:Nn \l__lawrence_ftabular_maxwd_dim { \dim_max:nn { \l__lawrence_ftabular_maxwd_dim } { \box_wd:N \l__lawrence_ftabular_item_box } } \tl_put_right:Nn \l__lawrence_ftabular_header_tl { & {\makebox[\l__lawrence_ftabular_maxwd_dim]{##1}} } } \tl_put_right:Nn \l__lawrence_ftabular_header_tl { \\ \hline } \tabular[#1]{ c| *{ \clist_count:n { #2 } } { c| } } \tl_use:N \l__lawrence_ftabular_header_tl } \ExplSyntaxOff \begin{document} \begin{ftabular}{Human capital and research, Reflects countries’ investment in education and research and development.

The KOMA script classes (and probably other classes as well) offer an option to set a binding correction. There are are few questions on the forum regarding how to determine the binding correction if one has a sample book (similar number of pages, same printing service). There are also (in German) two methods to do so described by Markus Kohm. However, I have a hard time understanding how to carry them out. I think this is caused by my total misunderstanding what binding correction even refers to. Often it is said that it is the amount of paper that is "lost due to" or "vanishes inside" the binding. However, I think I don't fully understand what is meant by this. I personally (maybe wrongly) think that it is the difference between the actually paper width and the width of the projection of the bound, curved, actual page inside the book onto a flat surface (the perceived page). The reason why I'm not sure about this is, that here the loss that is due to the actual binding is almost negligible compared to the loss of the curvature of the page. In fact this is more of a "curvature correction" than a "binding correction" then. Also, the curvature applies to the whole page (but is of course strongest close to the inner end of the page), does it really make sense to apply the correction only to the inner margin? It feels like the whole page layout should be recalculated taking the curvature of the page into account. To illustrate my problem: If I use Kohm's second method (open the book in the middle as you would read it; put a ruler in the middle; push a paper of the same width as the page against the ruler; measure how far this page hangs over the end of the book page), it makes a huge difference if I use a flexible paper and push it against the ruler such that follows the curvature of the page or if I use a stiff page and push it against the ruler while the page is parallel to the desk plane. For my reference example the first method gives a few mm and the second 2 cm. The second method takes the lost width due to the curvature into account (projection onto a flat plane) while the first one doesn't. As said, I think the second method is the correct one. But then again it is said that an upper limit for the binding correction is half of the height of the book (without cover) since the page at max needs to wrap around half of it. But why is this is a upper bound? In my example the loss due to the curvature of the pages is much larger than half of the book's width. I apologize if the question is hard to follow. I think it is a problem hard to describe in words, which is probably the reason why I'm such confused. Edit: I hope those two pictures help to illustrate the problem. This, first image, shamelessly stolen from this question shows that commonly used bindings for thesis like documents can cause a strong curvature of the page. This second picture is a drawing (sorry, I really can't draw) of mine to illustrate what I mean. The question in the end is, is the binding correction the page width minus r2 (the projection of the page onto a plane) r4 (the total, curved, visible area of the page) the difference between r1 and r3 I was under the assumption that the term binding allowance/binding correction is well defined and I'm simply not able to understand it. If the question is indeed opinion based (that is the binding allowance is not a well defined term and might to refer to whatever a typesetting thinks they should or should not correct for), I apologize for asking it. Since the discussion came up in the comments: I struggle with the term visibility (I'm not a native speaker). Is r3 considered visible or is r1 considered visible in the context of a binding allowance? I don't mean this in a philosophical way but as a genuine question.

I'm testing a manuscript for LaTeXML compatibility ahead of submission to the arXiv, and I've run into the following curious issue with tikz-cd when compiled in LaTeXML. In short, node names involving the \overline command are systematically misaligned. Here's a minimal example illustrating this behaviour: \documentclass{article} \usepackage{tikz-cd} \usepackage{latexml} \begin{document} % both node names are centered \[ \begin{tikzcd} Q \\ R \arrow[from=1-1,to=2-1] \end{tikzcd} \] % the name of node 1-1 is now right- and bottom-aligned \[ \begin{tikzcd} \overline{Q} \\ R \arrow[from=1-1,to=2-1] \end{tikzcd} \] \end{document} Here are screencaps of the resulting diagrams side by side: I'm hoping there's a quick workaround for this behaviour. My manuscript involves a number of commutative diagrams where \overline is used repeatedly, some of which are quite large. Note that the above code compiles perfectly in LaTeXML without any errors or warnings. EDIT: For whatever it's worth, here's what you get from the following code: \[ \begin{tikzcd} \overline{Q} & Q \\ Q & \overline{Q} \arrow[from=1-1,to=2-1] \arrow[from=2-1,to=2-2] \arrow[from=1-1,to=1-2] \arrow[from=1-2,to=2-2] \end{tikzcd} \] EDIT 2: The same diagrams but with \tikzcdset{nodes=draw, every diagram/.append style={baseline=(\tikzcdmatrixname-1-1.base)}} as suggested:

I would like to use .*TeX to make a variety of documents, including many with handwriting. I would like to avoid the glyphs exactly repeating since that looks less real. I previously found something to offset and rotate words, which definitely would help, but is there a way to have Metafont stroke endpoints be randomly offset? That would make each glyph a bit different, and in combination with other effects and on a handwriting style font, better approximate the look of handwriting as well as be another way to show rushed vs calmly written documents.

In my book I have two kinds of illustrations: photographs and sketches. These should be named respectively and should have distinct counters. This task can be done with the use of the \newfloat command of the memoir package. Great. Now, among both kinds of illustrations are present big graphics which should be rotated by the angle of 90 degrees - together with their captions. The tool aimed to perform this operation is sidewayfigure environment which is included in the rotating package. Fine. The remaining task is to integrate these two environments, but I am failed by it. Code: \documentclass[11pt,twoside]{memoir} \usepackage{mwe} \usepackage[utf8]{inputenc} \usepackage{graphicx} \usepackage{rotating} \setstocksize{180mm}{120mm} \settrimmedsize{180mm}{120mm}{*} \settypeblocksize{160mm}{100mm}{*} \setlrmargins{10mm}{*}{*} \setulmargins{10mm}{*}{*} \setheadfoot{0pt}{0pt} \settypeoutlayoutunit{mm} \checkandfixthelayout \newfloat{photo}{lop}{Photograph} \newfloat{sketch}{los}{Sketch} \begin{document} \begin{photo}[p] \includegraphics[width=\textwidth,height=.9\textheight]{example-image-a}% \caption{First photo}\label{photo:first} \end{photo} \begin{sketch}[p] \includegraphics[width=\textwidth,height=.9\textheight]{example-image-b}% \caption{First sketch}\label{sketch:first} \end{sketch} \begin{sidewaysfigure} \includegraphics[width=\textwidth,height=.5\textheight]{example-image-c}% \caption{First figure}\label{figure:second} \end{sidewaysfigure} \begin{photo} \begin{sideways} \includegraphics[width=\textwidth,height=.5\textheight]{example-image-a}% \caption{Second photo}\label{photo:second} \end{sideways} \end{photo} \end{document} By the way: How width and height optional arguments of \includegraphics work while are called within sidewaysfigure environment?

I remember strongly that there was a script called oolatex in texlive. Also in the documentation of tex4ht it is mentioned. Still I cannot find it in texlive any more. Is it available only in old releases? I don't want to use make4ht since I need full control. I prefer oolatex because it is closer to elementary. My intention is just to learn.

This is my first time making a bar plot using pgfplots. I am happy so far with what I have, but I still need some points. How can I make the top-most tick (14) coincide with the top boundary of the box? I do not like the tiny space between the top-most gridline and the top boundary of the box. I've already tried removing 14 from the key ytick but I don't like the result. I think the 14 has to stay. Suppose instead I decided to completely remove the top and right boundaries of the box. I know I can do that using the options axis x line*=bottom and axis y line*=left, but then I'd like to include arrowheads, at least for the y-axis. How to do that? Finally, I've managed to adjust the distance between successive bars by playing with the option x=0.8 cm. Is there a better way? Here is my code. I've also attached the figure. \documentclass[10pt]{book} \usepackage{tikz,pgfplots} \begin{document} \begin{tikzpicture}[every node/.style={font=\footnotesize}] \begin{axis}[ clip=false, ybar, ymajorgrids, grid style={dashed}, ymin=0, %axis x line*=bottom, %axis y line*=left, xlabel=Number of siblings, ylabel=Frequency, ytick pos=left, xtick pos=left, xtick=data, ytick={0,2,4,...,12,14}, bar width=.4cm, x=0.8cm, y=0.3cm, label style={font={\footnotesize \itshape}}, tick label style={font={\footnotesize \itshape}}, nodes near coords, nodes near coords align={vertical}, ] \addplot [fill=orange,] coordinates { (0,3) (1,13) (2,8) (3,3) (4,1) }; \end{axis} \end{tikzpicture} \end{document}

The following Stack Exchange answers describe two sort of clock faces which are very close to what I need : Chords between nodes on a clock-like diagram using TikZ As seen in the two examples, I would like to : keep the digits on exterior of circle control whether to display the arrows or lines - or, especially, not display them. I have been able to adjust the code of the two answers (details below) in order to : increase the divisions e.g. from 12 to 98 (but see below) obtain any single face and print it using most of size 8.5 x 11 paper I still would like : display only certain values around perimeter - e.g. 12, 3, 6, 9 as might be seen on a normal clock increase the total to 98 but ideally any value. The purpose is generally for looking at symmetry in modular arithmetic. LaTeX seems ideally suited for this vs. e.g. Gnuplot. omit the lines between "nodes" (or markings) potentially create hash marks on the circle at any increment I do not understand many parts of the two code examples, and I believe this is necessary to adjust the examples to my requirements. e.g. the function of modtweleve and TikZMGClockMath. I am using https://tikz.dev/ as a reference - so I suspect I am overlooking a number of resources. The small adjustments to the two answers in the link are IMHO trivial, and I do not think they need to be reproduced here unless requested. some details : in the accepted answer by user Jake, in \newcommand replace 12 with e.g. 50. However, this approach runs into memory problems as the value increases. adjust stepsize in {1,...,12} to e.g. stepsize in {5} gives the fifth clock face only. This is good. in the answer by user percusse I adjusted 12 to 13 and used a single \begin{scope} to control how many pictures are displayed. The resultant image(s) are closest to what I need ; however, I do not understand how the macro is working - e.g. the \modtwelve part. However, the value can be increased to 98 without any memory problems, and create a nice image. In fact, my exact goal is met by adjusting \TikZMGClockMath{3}{28} - giving a 7-fold pattern. Specifically, the drawing would be perfect if the integers between e.g. 0 and 28 were omitted. in that answer, I commented out line 19-29 - from \draw and the first } that appears - to 'omit' the lines (vectors). This seems good. UPDATE: I added hashmarks with this code: \foreach \angle / \label in {90/0, 38.6/14, -12.8/28, -64.2/42, -115.6/56, -167/70, -218.4/84} ... which is good to show 7-fold symmetry, but they are not on the perimeter. The \draw commands adjust the position of a node or line width by the \angle. This is easy to adjust. See https://tikz.dev/pgffor UPDATE I found an inelegant way to add hashmarks - right after the above code, put this in: \draw[line width=0.5pt] (\angle:8.0cm) -- (\angle:8.5cm); } \foreach \angle in {86.3265, 86.3265, 82.6531, [.. skipping...] -258.98, -262.653, -266.327} the values are pre-calculated using awk. It would be nice to reduce that into a \foreach, multiplying the value of the example (360/98). Then, (360/98) could be any division of the circle. I tried asking on the original post, but I do not have the requisite reputation. If there is a better approach, I'd be glad to change this question.

I have tried to create a cover for my book that is beautiful and visually appealing. Since the book deals with topics such as relativity, clocks, four-vectors, spacetime, the calculus of variations, and many other fascinating ideas, I imagined clocks being sucked into an unknown spacetime and deformed in the style of Salvador Dalí. The clocks become distorted until they break apart into many fragments, including the smallest and most symbolic components, such as the central pin and the internal spring.

This is a follow up from Another mathjax/mathml question. MWE test.tex: \documentclass{book} \usepackage{tikz} \begin{document} \chapter{A test} \section{A section in the chapter} \begin{center} \tikz{ \draw (0,0) -- (1,0); } % \begin{tikzpicture} % \draw (0,0) -- (1,0); % \end{tikzpicture} \end{center} \[ a = b \] \begin{equation} \chi = \int_{-\infty}^{\infty} a(x) \exp{\left[ i 2 \pi x f \right]} dx \end{equation} \end{document} and test.cfg \Preamble{xhtml,mathml,mathjax} \catcode`\:11 \Configure{IMG} {\ht:special{t4ht=\ifmathml <\a:mathml semantics><\a:mathml annotation-xml encoding="application/xhtml+xml">\fi<img\Hnewline \ifmathml xmlns="http://www.w3.org/1999/xhtml"\fi\Hnewline src="\a:imgdir }\PauseMathClass} {\ht:special{t4ht=" alt="}} {" } {\ht:special{t4ht=" }} {\EndPauseMathClass\ht:special{t4ht=\xml:empty>\ifmathml </\a:mathml annotation-xml></\a:mathml semantics>\fi}} \catcode`\:12 \begin{document} \EndPreamble The config is probably unnecessary for users of vanilla texlive, but required in my case (see link to original question). make4ht is called as make4ht -l -c test.cfg test.tex As written, both equations after the \tikz{...} render as Math input error. If replaced by the code commented out i.e. \begin{tikzpicture} \draw{...} \end{tikzpicture} the rendering is normal. Thanks for your attention.

Although the newcomputermodern usepackages in LaTeX offer more Unicode accents, when I tried to convert them to (like \Vecbelow{a}), I found that Unicode accents must be placed after the letter, while LaTeX accents are placed before the letter and enclose it. It cannot directly enclose letters like the native LaTeX accents command to this letter here: . \documentclass{article} \usepackage{newcomputermodern} \begin{document} \t{a} a\symbol{"0362} \symbol{"0362}a \end{document}

With the following MWE: \documentclass[tikz,border=5pt]{standalone} \usepackage{tikzpeople} \begin{document} \begin{tikzpicture} \node[businessman, minimum size=1.5cm] {}; \end{tikzpicture} \end{document} However, in the terminal output, we know that: Missing character: There is no * in font nullfont! Missing character: There is no 4 in font nullfont! Missing character: There is no . in font nullfont! Missing character: There is no 7 in font nullfont! Missing character: There is no 0 in font nullfont! Missing character: There is no 2 in font nullfont! Missing character: There is no 9 in font nullfont! Missing character: There is no 4 in font nullfont! Missing character: There is no p in font nullfont! Missing character: There is no t in font nullfont! Is that a bug with tikzpeople? Any quick fix to prevent this?

I am trying to draw a graph (function of the form sin()*exp(-x^2)) inside an ellipse. How do I fit the graph inside the ellipse? I don't know how to scale and position it correctly. \documentclass[tikz]{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture} \draw[line width=1.2,fill=white] (1.5,0.5) ellipse (1.5 and 0.5); \draw[scale=0.1, domain=-20:20, samples=500, smooth, variable=\x, blue] (1.5,0.5) plot ({\x}, {0.5*sin(\x) * exp(-0.02*(\x)*(\x))}); \end{tikzpicture} \end{document} I want to produce something like:

As far as I know, the array environment needs to be in math mode. Not surprisingly, the following code fails on TeXlive 2025 on Overleaf with the error message "missing $ inserted". \documentclass{article} \begin{document} \begin{array}{c} x \end{array} \end{document} However, the same code compiles without any errors on my local TeXlive 2026. I haven't found any documentation on the change of the behavior of array from 2025 to 2026, so I am curious how it is able to run outside of math mode here. kpsewhich latex.ltx returns /usr/local/texlive/2026basic/texmf-dist/tex/latex/base/latex.ltx and kpsewhich array.sty returns /usr/local/texlive/2026basic/texmf-dist/tex/latex/tools/array.sty The file resides alone in a separate folder of its own. So, it seems that the standard texlive distribution is used and nothing else. Any ideas?

Is there a macro or something out there to convert the style of headings into Chinese? By which I mean, to make something like \documentclass{article} \usepackage{xeCJK} \setCJKmainfont{Noto Sans CJK TC} \begin{document} \section{甲章} \subsection{甲節} \subsection{乙節} \end{document} display 壹、甲章 一、甲節 二、乙節 Preferably, the numberings should be customizable between 壹貳, 一二, 甲乙, (一)(二), 1 2, and so on. For reference, I am using XeLaTeX and the xeCJK package on the Overleaf platform. EDIT 7/21 @Explorer's answer does not fix the Table of Contents' headings. See this follow-up question for more info. I figured from other posts that you shouldn't ask two questions in one post.

I have this MWE I extracted from my document on Overleaf (compiled in LuaLaTeX, which is necessary for my project): \documentclass[]{report} \begin{document} see here \cite{ref1,ref2} \bibliographystyle{IEEEtran} \bibliography{references} \end{document} and its giving me the citations as "see here [1,2]", instead of "see here [1], [2]". This is the exact opposite of the problem found in this question, though it seems both of us have our packages at their default. Thanks in advance for any suggestions EDIT: The original question had it written that I wanted no brackets (i.e. 'see here 1,2'). This was due to shoddy editing of the question on my part. I've updated my required citation format is of the form [1], [2], i.e., with square brackets around each and every citation call-out. Thank you. EDIT 2: I have accepted the answer by Mico for now, as it more closely conforms to the question, though Explorer's is also valid and should be looked at. In the comments of the latter answer, Explorer and I agreed that a simpler solution than both probably should exist, considering my ask is 1) apparently the default in the question I linked to above (though that question has no MWE and is quite old), and 2) it is apparently the more correct way to currently cite IEEE, as according to the most updated reference guide (2025) -- see Section 1. Also see here. As such, I suppose the question is still open to discussion, though both current answers are valid (and both answerers are kindly thanked for their time!).

I have a line of text that LaTeX refuses to group into one line even though it fits. I used \thinspace the whole way which has worked every one of the hundreds of other times I've tried it, but not this time. \documentclass{book} \usepackage[margin=1in]{geometry} \begin{document} \noindent \begin{minipage}{3.5in} (other text in other rows) angle\thinspace into\thinspace two\thinspace congruent\thinspace $30^\circ\!-60^\circ\!-90^\circ$\thinspace right\thinspace triangles ($\triangle$s\thinspace BMA\thinspace and\thinspace BMC),\thinspace the \end{minipage} \end{document} which the program breaks in weird ways: Is there another way to further force text into a given space (especially as one line, i.e. a "line minipage") that can be implemented cleanly as part of a larger paragraph? (I'm using the book class and, if it matters, TeXstudio).

I'm creating a table in LaTeX with images and multi-line text in one column. The text in the "Observaciones" (Observations) column is overflowing outside the table boundaries and not wrapping properly within the cell. The third row's text wraps correctly, but the first two rows' text extends beyond the table width. I'm using \makecell[l] but it's not containing the text properly. How can I ensure the text stays within the cell boundaries and wraps properly regardless of content length? All rows should align at the top with text contained within the column width. The images sizes are 1257x1262 px \documentclass{article} \usepackage{geometry} \usepackage{makecell} \usepackage{graphicx} \geometry{ letterpaper, margin=3cm } \setlength{\marginparwidth}{2cm} \begin{document} \begin{table}[H] \centering \small \begin{tabular}{ >{\raggedright\arraybackslash}m{2cm} >{\centering\arraybackslash}m{3.4cm} >{\centering\arraybackslash}m{3.4cm} >{\raggedright\arraybackslash}m{6cm} } \hline \textbf{Fase} & \textbf{$L_1$} & \textbf{$L_3$} & \textbf{Observaciones} \\ \hline Poros & \includegraphics[width=3.3cm]{example-image} & \includegraphics[width=3.3cm]{example-image} & \makecell[tl]{ $N$: 127,090\\ $P_j$: 1.52\\ $T_G$: -1.16\\ Fuerte linealidad vertical } \\ \hline Óxido & \includegraphics[width=3.3cm]{example-image} & \includegraphics[width=3.3cm]{example-image} & \makecell[tl]{ $N$: 2,228\\ $P_j$: 1.09\\ $T_G$: -0.18\\ Débil anisotropía } \\ \hline Plagioclasa & \includegraphics[width=3.3cm]{example-image} & \includegraphics[width=3.3cm]{example-image} & \makecell[tl]{ $N$: 1,065\\ $P_j$: 1.29\\ $T_G$: -0.73\\ Orientación preferencial moderada sin embargo, se concentra en el eje Z } \\ \hline \end{tabular} \caption{Análisis de orientación de fases de la muestra L187.} \label{tab:stereonets_l187} \end{table} \end{document}
