\noindent The \textsf{mathfont} package adapts unicode text fonts for math mode. The package allows the user to specify a default unicode font for different classes of math symbols, and it provides tools to change the font locally for math alphabet characters. When typesetting with Lua\TeX, \textsf{mathfont} adds resizable delimiters, big operators, and a MathConstants table to text fonts.\par}

A few characters appear multiple times in this list. When that happens, it means that \textsf{mathfont} defines the control sequence for multiple keywords. If you call |\mathfont| for only one of those keywords, your symbol will appear in the font associated with that keyword. If you call |\mathfont| on multiple keywords, the package uses the font associated with the default keyword/font for that character. Table~1 lists the default keyword for each command that appears multiple times in this document. If you need unicode encoding slot numbers for character metric adjustments, each symbol corresponds to its standard unicode encoding value, with the exception of the fake angle brackets.

\section{Loading and Basic Functionality}
-Loading fonts for math typesetting is more complicated than for regular text. First, selecting fonts for math mode, both in plain \TeX\ and in the \textsc{nfss}, involves additional macros above and beyond what we need to load text fonts. Second, \TeX\ expects fonts for math to contain extra information for formatting equations.\footnote{Specifically, this extra information is a set of large variants, math-specific parameter values associated with individual characters, and a MathConstants table. Also, math fonts often use slightly wider bounding boxes for letters in math mode---the Computer Modern $f$ is a well-known example. (Compare \fbox{$f$} and \fbox{\texttt{f}}.) For this reason, \textsf{mathfont} also provides an interface to enlarge the bounding boxes of Latin letters when they appear in math mode. See section 5 for details.} Broadly speaking, we say that a \textit{math font} contains this extra information, whereas a \textit{text font} does not, and typesetting math with glyphs from one or more text fonts usually results in equations that are less aesthetically pleasing than using a properly prepared math font. The functionality of \textsf{mathfont} then is twofold: (1) provide a wrapper around the \textsc{nfss} commands for math typesetting that serves as a high-level interface; and (2) implement Lua\TeX\ callbacks that artificially convert text fonts into math fonts at loading.\footnote{Values for MathConstants table are different from but inspired by Ulrik Vieth, ``Understanding the \AE sthetics of Math Typesetting,'' (Bacho\TeX\ Conference, 2008) and Ulrik Vieth ``OpenType Math Illuminated,'' \textit{TUGboat} 30 (2009): 22--31. See also Bogus\l aw Jackowski, ``Appendix G Illuminated,'' \textit{TUGboat} 27 (2006): 83--90.} Although \textsf{mathfont} tries its best to get your fonts right, it may run into trouble when picking fonts to load. If this happens, you should declare your font family and shapes in the \textsc{nfss} before setting any fonts with \textsf{mathfont}.

If this happens, you should declare your font family and shapes in the \textsc{nfss} before setting any fonts with \textsf{mathfont}.
You must use one of \XeLaTeX\ or Lua\LaTeX\ to typeset a document with \textsf{mathfont}. You can load \textsf{mathfont} with the standard |\usepackage{mathfont}| syntax, and the package accepts three optional arguments. If you use Lua\TeX, the options |adjust| or |no-adjust| will manually specify whether \textsf{mathfont} should adapt text fonts for math mode, and \textsf{mathfont} selects |adjust| by default. If you use \XeTeX, \textsf{mathfont} cannot adjust any font objects with Lua callbacks, and either of these package options will cause an error.\footnote{With \XeLaTeX, \textsf{mathfont} does not add big operators or resizable delimiters. This means you will have to use the Computer Modern defaults, load a separate math font for resizable characters, or end up with a document where large operators and delimiters do not scale like they do normally.} For this reason, using Lua\TeX\ with \textsf{mathfont} is recommended as of version 2.0. If you load \textsf{mathfont} with any other optional argument, the package will interpret it as a font name and call |\setfont| (described in the next section) on your argument. Doing so selects that font for the text of your document and for the character classes in the upper section of Table~1.
-The \textsf{mathfont} package is closely related to several other \LaTeX\ packages. The functionality is closest to that of \textsf{mathspec} by Andrew Gilbert Moschou, which is compatible with \XeTeX\ only and selects characters from text fonts for math.\footnote{Andrew Gilbert Moschou, ``\textsf{mathspec}---Specify arbitrary fonts for mathematics in \XeTeX,'' \link{https://ctan.org/pkg/mathspec}.} The \textsf{unicode-math} package is the standard \LaTeX\ package for loading actual unicode math fonts, and if you have a unicode font with proper math support, rather than a text font that you want to use for equations, consider using this package instead of \textsf{mathfont}.\footnote{Will Robertson, et al., ``\textsf{unicode-math}---Unicode mathematics support for XeTeX and LuaTeX,'' \link{https://ctan.org/pkg/unicode-math}.} Users who want to a text font for math with pdf\LaTeX\ should consider Jean-Fran\c cois Burnol's \textsf{mathastext} because \textsf{mathfont} is incompatible with pdf\TeX.\footnote{Jean-Fran\c cois Burnol, ``\textsf{mathastext}---Use the text font in maths mode,'' \link{https://ctan.org/pkg/mathastext}. In several previous versions of this documentation, I mischaracterized the approach of \textsf{mathastext} to \TeX's internal mathematics spacing. In fact, \textsf{mathastext} preserves and in some cases extends rules for space between various math-mode characters.} Finally, you will probably be better off using \textsf{fontspec} if your document does not contain any math.\footnote{Will Robertson and Khaled Hosny, ``\textsf{fontspec}---Advanced font selection in \XeLaTeX\ and Lua\LaTeX,'' \link{https://ctan.org/pkg/fontspec}.} The \textsf{fontspec} package is designed to load TrueType and OpenType fonts for text and provides a high-level interface for selecting OpenType font features.

The |base| mode supports limited OpenType features, but the features will work for both text and math. When \textsf{mathfont} loads a font, it does so twice, once in |node| mode, which is primarily for setting the text font with \vrb\setfont, and once in |base| mode, which is for the package's other font declarations.

For example, the macro |\newmathrm| looks like

-The \textsf{mathfont} package provides six user-level commands to change positioning of characters in math mode. The commands |\CharmLine| and |\CharmFile| affect specific to various characters. (Charm stands for ``character metric.'') The argument of |\CharmLine| should be a list of integers and/or asterisks separated by commas and/or spaces, and Table~\ref{Charm} shows how many integers you need for different types of characters. The first integer from the argument should be a unicode encoding number, and that tells \textsf{mathfont} how to handle the remaining values.
+The \textsf{mathfont} package provides six user-level commands to change bounding box, size, and accent positioning of characters in math mode. The command |\CharmLine| sets these features for a single math-mode character relative to its text-mode counterpart, and |\CharmFile| does the same thing for multiple characters at a time. (Charm stands for ``character metric.'') The argument of |\CharmLine| should be a list of integers and/or asterisks separated by commas and/or spaces, and Table~\ref{Charm} shows how many integers you need for different types of characters. The first integer should be the unicode encoding value of the character to be adjusted, and \textsf{mathfont} interprets the remaining numbers as follows.
\begin{itemize}
-\item If the unicode value corresponds to a Latin letter, the next two integers tell Lua\TeX\ how much to stretch the left and right sides of the glyph's bounding box when it appears in math mode. The final two integers determine horizontal placement of top and bottom math accents respectively.
-\item If the unicode value corresponds to a delimiter, the radical (surd) symbol, or a big operator, you will need to specify 16 pairs numbers, for a total of 32 entries. The first 15 pairs are horizontal and vertical scale factors that \textsf{mathfont} uses to create large variants, where successive pairs correspond to the next-larger glyph. The last two integers determine horizontal placement of top and bottom math accents respectively.
-\item If the unicode value corresponds to any other symbol, you should specify two more integers, which will determine the horizontal placement of top and bottom math accents respectively.
+\item If the unicode value corresponds to a Latin letter, you should specify four more numbers.

-For most applications, you can probably ignore charm information altogether, but if you find bounding boxes or accent placement to be off slightly or if you want to change the scaling for a delimiter or big operator, you should try calling |\CharmLine| with different values to see what works.

-% This section deals with local font changes. The |\newmathfontcommand| creates macros that change the font for math alphabet characters and is basically a wrapper around |\DeclareMathAlphabet|. First we code |\M at check@csarg|, which accepts two arguments. The |#1| argument is the user-level command that called |\M at check@csarg|, which we use for error messaging, and |#2| should be a single control sequence. The way |\M at check@csarg| scans the following tokens is a bit tricky: (1) check the length of the argument using |\M at check@arglength|; and (2) check that the argument is a control sequence. If the user specifies an argument of the form |{..}|, i.e.\ extra text inside braces, the |\ifcat| will catch it and issue an error. If |\M at check@csarg| likes the input, it sets |\ifM at good@arg| to true, and otherwise, it sets |\ifM at arg@good| to false.

\section{Loading and Basic Functionality}
-Loading fonts for math typesetting is more complicated than for regular text. First, selecting fonts for math mode, both in plain \TeX\ and in the \textsc{nfss}, involves additional macros above and beyond what we need to load text fonts. Second, \TeX\ expects fonts for math to contain extra information for formatting equations.\footnote{Specifically, this extra information is a set of large variants, math-specific parameter values associated with individual characters, and a MathConstants table. Also, math fonts often use slightly wider bounding boxes for letters in math mode---the Computer Modern $f$ is a well-known example. (Compare \fbox{$f$} and \fbox{\texttt{f}}.) For this reason, \textsf{mathfont} also provides an interface to enlarge the bounding boxes of Latin letters when they appear in math mode. See section 5 for details.} Broadly speaking, we say that a \textit{math font} contains this extra information, whereas a \textit{text font} does not, and typesetting math with glyphs from one or more text fonts usually results in equations that are less aesthetically pleasing than using a properly prepared math font. The functionality of \textsf{mathfont} then is twofold: (1) provide a wrapper around the \textsc{nfss} commands for math typesetting that serves as a high-level interface; and (2) implement Lua\TeX\ callbacks that artificially convert text fonts into math fonts at loading.\footnote{Values for MathConstants table are different from but inspired by Ulrik Vieth, ``Understanding the \AE sthetics of Math Typesetting,'' (Bacho\TeX\ Conference, 2008) and Ulrik Vieth ``OpenType Math Illuminated,'' \textit{TUGboat} 30 (2009): 22--31. See also Bogus\l aw Jackowski, ``Appendix G Illuminated,'' \textit{TUGboat} 27 (2006): 83--90.} Although \textsf{mathfont} tries its best to get your fonts right, it may run into trouble when picking fonts to load. If this happens, you should declare your font family and shapes in the \textsc{nfss} before setting any fonts with \textsf{mathfont}.

(Compare math-mode {\fboxsep=0pt\fbox{$f$}} and italic {\fboxsep=0pt\fbox{\textit{f}}}.) For this reason, \textsf{mathfont} also provides an interface to enlarge the bounding boxes of Latin letters when they appear in math mode. See section 5 for details.} Broadly speaking, we say that a \textit{math font} contains this extra information, whereas a \textit{text font} does not, and typesetting math with glyphs from one or more text fonts usually results in messier equations than using a properly prepared math font. The functionality of \textsf{mathfont} then is twofold: (1) provide a wrapper around the \textsc{nfss} commands for math typesetting that serves as a high-level interface; and (2) implement Lua\TeX\ callbacks that artificially convert text fonts into math fonts at loading.\footnote{Values for MathConstants table are different from but inspired by Ulrik Vieth, ``Understanding the \AE sthetics of Math Typesetting,'' (Bacho\TeX\ Conference, 2008) and Ulrik Vieth ``OpenType Math Illuminated,'' \textit{TUGboat} 30 (2009): 22--31.

If this happens, you should declare your font family and shapes in the \textsc{nfss} before setting any fonts with \textsf{mathfont}.
You must use one of \XeLaTeX\ or Lua\LaTeX\ to typeset a document with \textsf{mathfont}. You can load \textsf{mathfont} with the standard |\usepackage{mathfont}| syntax, and the package accepts three optional arguments. If you use Lua\TeX, the options |adjust| or |no-adjust| will manually specify whether \textsf{mathfont} should adapt text fonts for math mode, and \textsf{mathfont} selects |adjust| by default. If you use \XeTeX, \textsf{mathfont} cannot adjust any font objects with Lua callbacks, and either of these package options will cause an error.\footnote{With \XeLaTeX, \textsf{mathfont} does not add big operators or resizable delimiters. This means you will have to use the Computer Modern defaults, load a separate math font for resizable characters, or end up with a document where large operators and delimiters do not scale like they do normally.} For this reason, using Lua\TeX\ with \textsf{mathfont} is recommended as of version 2.0. If you load \textsf{mathfont} with any other optional argument, the package will interpret it as a font name and call |\setfont| (described in the next section) on your argument. Doing so selects that font for the text of your document and for the character classes in the upper section of Table~1.
-The \textsf{mathfont} package is closely related to several other \LaTeX\ packages. The functionality is closest to that of \textsf{mathspec} by Andrew Gilbert Moschou, which is compatible with \XeTeX\ only and selects characters from text fonts for math.\footnote{Andrew Gilbert Moschou, ``\textsf{mathspec}---Specify arbitrary fonts for mathematics in \XeTeX,'' \link{https://ctan.org/pkg/mathspec}.} The \textsf{unicode-math} package is the standard \LaTeX\ package for loading actual unicode math fonts, and if you have a unicode font with proper math support, rather than a text font that you want to use for equations, consider using this package instead of \textsf{mathfont}.\footnote{Will Robertson, et al., ``\textsf{unicode-math}---Unicode mathematics support for XeTeX and LuaTeX,'' \link{https://ctan.org/pkg/unicode-math}.} Users who want to a text font for math with pdf\LaTeX\ should consider Jean-Fran\c cois Burnol's \textsf{mathastext} because \textsf{mathfont} is incompatible with pdf\TeX.\footnote{Jean-Fran\c cois Burnol, ``\textsf{mathastext}---Use the text font in maths mode,'' \link{https://ctan.org/pkg/mathastext}. In several previous versions of this documentation, I mischaracterized the approach of \textsf{mathastext} to \TeX's internal mathematics spacing. In fact, \textsf{mathastext} preserves and in some cases extends rules for space between various math-mode characters.} Finally, you will probably be better off using \textsf{fontspec} if your document does not contain any math.\footnote{Will Robertson and Khaled Hosny, ``\textsf{fontspec}---Advanced font selection in \XeLaTeX\ and Lua\LaTeX,'' \link{https://ctan.org/pkg/fontspec}.} The \textsf{fontspec} package is designed to load TrueType and OpenType fonts for text and provides a high-level interface for selecting OpenType font features.

In fact, \textsf{mathastext} preserves and in some cases extends rules for space between various math-mode characters.} Finally, you will probably be better off using \textsf{fontspec} if your document does not contain any math.\footnote{Will Robertson and Khaled Hosny, ``\textsf{fontspec}---Advanced font selection in \XeLaTeX\ and Lua\LaTeX,'' \link{https://ctan.org/pkg/fontspec}.} The \textsf{fontspec} package is designed to load TrueType and OpenType fonts for text and provides a high-level interface for selecting OpenType font features.

\noindent The \textsf{mathfont} package adapts unicode text fonts for math mode. The package allows the user to specify a default unicode font for different classes of math symbols, and it provides tools to change the font locally for math alphabet characters. When typesetting with Lua\TeX, \textsf{mathfont} adds resizable delimiters, big operators, and a MathConstants table to text fonts.\par}
