Fonts & Character Sets ⇒ Redefine % character mapping

[rhino7890]

I'm trying to remap the % character in mathmode to a different font. Typically, if I were to remap a character, I would do something like this:

Code: Select all

\DeclareSymbolFont{mymathvariables}{<encoding>}{<fontfamily>}{<weight>}{<style>}
\DeclareSymbolFontAlphabet{\mathnormal}{mymathvariables}

\DeclareMathSymbol{$}{\mathalpha}{mymathvariables}{"24}

which would map the "$" character to <fontfamily> in mathmode instead of the default fontfamily. However, remapping the % character is a little tricky as the % character is the comment symbol in LaTeX. So,

Code: Select all

\DeclareMathSymbol{%}{\mathalpha}{mymathvariables}{"25}

doesn't work as the LaTeX parser doesn't interpret anything after the % sign.Likewise, if I try something like this

Code: Select all

\DeclareMathSymbol{\%}{\mathalpha}{mymathvariables}{"25}

I get an error saying that "LaTeX Error Command `\%' already defined."

Does anyone know how to get around this problem? Thanks.

So I figured out a solution:

Code: Select all

\catcode`\%=12
\DeclareMathSymbol{%}{\mathpunct}{mymathvariables}{"25}
\catcode`\%=14
