Is it possible to identify the font used in a specific document/picture?  Answers to this question should identify:   Possible methods to do this (perhaps one answer per method) and adequately describe how to use it (as opposed to merely stating it); Ways of finding the identified fonts, if possible (free or not); and Any prerequisites associated with the method used, if required (for example, "In order to use method X, your document has to be in format Y").   This question is meant as an FAQ, based on an . Its aim is to facilitate the community with the general procedures involved in font identification. Similar cases are solved on a per-usage basis on 's  tag.

Although I have seen many similar questions, none has been useful.   The question is quite simple: How do I reproduce the highlighted numerals in the image below?    Note that the form of the numerals addressed in questions as  is different from this one.  Thank you in advance!

I'm currently typing a mathematical document which counts many sum symbols. I frequently use the align environment to render equations, although the default behaviour of this environment is to render the equations in displaystyle, which in my opinion wastes vertical space. I therefore have added \textstyle at the beginning of each line of math in this environment, but I'm looking for a more convenient solution.   So is there an environment that is similar to align with the exception it displays textstyle math by default ? Thank you.

I have an equation that is too long to fit on one line:  x = a + b + c + d + e + f   as an example of what it looks like. What is the correct way to handle this? Do i break it up over multiple lines? Do I decrease the font? I am using LyX as my editor.

I am wondering if there is a way to change the math font temporarily, similar to the way it can be done in text mode:  {\ttfamily Some text in typewriter font.}   Is there a way to do $\ttfamily a + b = c$ for example?  I know I could do $\mathtt{a + b = c}$, just like I could do \texttt{text}, but sometimes the other way results in cleaner code.  Please mind I am not looking for something like $\texttt{monospace} \textit{ in math.}$ I want to be able to write complicated formulas without having to mention the font in every word, as I would do in, for example, $\Sigma_{\mathtt{i} = 1}^{\mathtt{n}}$.

I'm trying to figure out a decent solution (especially from the SEO side) for embedding fonts in web pages. So far I have seen , which doesn't even work on Firefox, and . The second solution is for titles only. Is there a solution available for full text? I'm tired of the standard fonts for web pages.  Thanks!

What OpenType math fonts are there available for usage in TeX/LaTeX, e.g. with the unicode-math package?  Here is a MWE which you can use to show off the font.  \documentclass{article} \pagestyle{empty}  \usepackage{amsmath} \DeclareMathOperator\Res{Res} \newcommand*\diff{\mathop{}\!\mathup{d}}  \usepackage{amsthm} \newtheorem{theorem}{Theorem}  \usepackage{unicode-math}  %%% % Set up you text and math fonts %%%  \begin{document}  \begin{theorem}[Residue theorem]   Let $f$ be analytic in the region $G$ except for the isolated   singularities $a_1,a_2,\dots,a_m$. If $\gamma$ is a closed   rectifiable curve in $G$ which does not pass through any of the   points $a_k$ and if $\gamma\approx 0$ in $G$, then   \[     \frac{1}{2\pi i} \int\limits_\gamma f\Bigl(x^{\mathbf{N}\in\mathbb{C}^{N\times 10}}\Bigr)     = \sum_{k=1}^m n(\gamma;a_k)\Res(f;a_k)\,.   \] \end{theorem}  \begin{theorem}[Maximum modulus]   Let $G$ be a bounded open set in $\BbbC$ and suppose that $f$ is a   continuous function on $G^-$ which is analytic in $G$.

This is a little bit off topic as it is not exactly related to TeX.  I saw recently that  was updated to 1.020 which comes with math table support.  Does any one had a chance to play with this font and use it with unicode-math, and in particular with the LuaTeX engine?  I am very interested in purchasing a complete set of this nice fonts family. However I am concerned about its usability with the unicode-math package. Unlike Cambria Math or XITS Math, Minion Math does not come with a single font, instead it has 20 (4 weights 5 optical sizes) fonts. So it will be better to know how it works before spending 700 euro.  In particular, say the following minimal document, will it use correct optical size of the fonts for each of the three formulas? I had trouble with using correct optical size of Minion Pro fonts with fontspec. I worked it out with the SizeFeatures and OpticalSize. However, I am not so sure if the same strategy will work for Minion Math with unicode-math. In addition, in Cambria Math, etc., the bold symbols and alphabets are chosen directly from the unicode math enabled fonts. But in Minion Math, from the glyph tables on their websites, there seems no bold alphabets in each font. So will the mathbf in the document below work out of box?  \documentclass{article} \usepackage{fontspec} \setmainfont{Minion Pro} \usepackage{unicode-math} \setmathfont{Minion Math} % or what ever fonts name actually is  \begin{document} \fontsize{5}{5}\selectfont \[ \mathbf{E} = mc^2 \] \fontsize{10}{10}\selectfont \[ \mathbf{E} = mc^2 \] \fontsize{36}{36}\selectfont \[ \mathbf{E} = mc^2 \] \end{document}

I realize similar questions have been asked before but I am not satisfied with any of the answers I've seen. I would like to use the Cyrillic letter Ш to denote a particular group in mathematics. Most solutions involve using OT2 or T2A encoding; for example, at . However, this makes the other text in the document look bad.   For example, using the solution above, I get    while I would like to have     The first seems to be shaded strangely and the characters don't seem to align right.  Does anyone know how I can write the character Ш (in math mode) without changing the default font for the rest of the text?

Textual subscripts like in W_{total} should be typeset in an upright text font (so that code isn't good practice), as has been  in   . Now there are several ways to achieve this, and I'm somewhat confused which I should use:   W_{\rm total} is nice and short, and appears to work in all circumstances, but I expect LaTeX people will frown upon it :-) Is there any good reason against this? W_{\mathrm{total}} &ndash; is this the LaTeX equivalent of the \rm approach? W_{\textnormal{total}}  as total is text and not math&nbsp;... In , Ulrike Fischer suggests a more complicated approach. Even W_{\operatorname{total}} appears to work, but it seems inappropriate.   Note: I always assume here that amsmath is loaded.  I've already asked some questions above, but my main question is: which of these options is the best practice for textual subscripts?    Let me point out why I haven't mentioned \text, \textrm or \textup above. Those commands (mostly) keep the font of the context they're used in, e.g., in an italic context, \text and \textrm would give italic subscripts, and all three yield bold subscripts in a bold context.  Final note: This question is similar to, but not the same as all those  about the  between , , , ,  that have been asked before. Maybe it's still a duplicate&nbsp;...

I use the \newtxmath as the math font in my document and \newtxtext for the text. This seems to work fine, but I need to replace some math symbols which seem to me not as nice as their default Latin Modern Math counterpart. The symbols I need to replace, e.g., are:   \int and \sum: they look so high and big,  \infty: looks too small, and  \partial and \pi: looks strange too.   I have searched for similar or near question like this one (), but I haven't been very successful in reusing the answer therein in my case.   My MWE is:  \documentclass{scrartcl} \usepackage{amsmath,amssymb} \usepackage{newtxtext,newtxmath} \begin{document}  \noindent ABCDEFGHIJKLMNOPQRSTUVWXYZ \\ abcdefghijklmnopqrstuvwxyz \\ $abcdefghijklmnopqrstuvwxyz$ \\ $ABCDEFGHIJKLMNOPQRSTUVWXYZ$ \\ $a\alpha\beta\gamma\delta\epsilon\varepsilon\zeta\eta\theta\vartheta\iota\kappa\varkappa\lambda\mu\nu\xi o\pi\varpi\rho\varrho\sigma\varsigma\tau\upsilon\phi\varphi\chi\psi\omega$ \\ $\Gamma\Delta\Theta\Lambda\Xi\Pi\Sigma\Upsilon\Phi\Psi\Omega$ \\ $\mathbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$ \[   \frac{1}{2\pi i}\int_\gamma f(x) = \sum_{k=1}^m n(\gamma;a_k) \cdot \text{Res}(f;a_k). \] \[ G(\omega)=\int_{-\infty}^{\infty}g(t)e^{-j\omega t} dt \] And this is nonmath text.  \end{document}   I appreciate your help.

First, I don't know much about creating fonts.  I work with a childrens book author and want to create a font from her handwriting. This means that I have to have more then one character per letter and use them at random.  I've found ways of creating a font from your handwriting (googled) – but not that has this capability. Anyone with ideas??  Thanks!

What is the font that's used in Mac OS X's graphical user interface (GUI), in the menus, dialog boxes, etc.? Is it different from what was used in the classic Mac OS (i.e. OS 9 or older)? If so, what are the fonts back then? I like the font but never knew what it was. Thanks.

During a Pages update which was pushed out a few months ago, Pages obtained the ability to write equations using LaTeX or MathML commands. According to an Apple Support article, the size and color of the equation can be changed ():  The equation appears at the insertion point in your document (or before the selected text). The equation is an inline object, the same size and color as the surrounding text. If you change the size or color of the surrounding text, the size and color of the equation’s font also change.  This does not mention anything about the font used for the equation itself, which seems to be something similar to a Times New Roman font. Is there any way to change the font used, preferably to something like Latin Modern Math? I was considering the possibility of replacing the font file Pages uses with a downloaded Latin Modern Math font file, but I'm not sure what to replace. Could I replace Times New Roman in /System/Library/Fonts/ or something like that?

For mathematics, is it ever disadvantageous to use \left(  and \right)  in equations?  I can't see any way that doing this would hinder the typesetting, so why isn't () just converted into \left( \right) automatically? This would save a lot of typing.  Cheers!
