I would like to know the name (code) of fonts in (La)TeX. Let me explain myself:
When I want to import a symbol from a different font, I type something like
\DeclareFontFamily{U} {cmsy}{}
Here cmsy is the (La)TeX encoding, (La)TeX name, (La)TeX code or whatever you want for the family Computer Modern (which is set by default in LaTeX).
If I want to import a symbol from the mathabxpackage (in this case subsetsymbol) I can write
\DeclareFontFamily{U}{matha}{\hyphenchar\font45}
Now the code is matha.
My question is:
Suppose I want to import a single character from Century Modern TT font. What code has it in
(La)TeX? Which is the equivalent forcmsyandmathain any other font?
