Maybe an easier question would be the following. To compare text fonts I could do the following (pseudocode): \font\a="Some font:mapping=tex-text" \font\b="Some Other Font:mapping=tex-text"
\def\printline#1{{\a #1}{\b #1}} \somecommandtoloopoversomerange{0}{1000}{\printline{\char\loopnumber}} This command (\a and \b) has very low penalty. My question is: how can I achieve the same low-level with math? The command \setmathfont{Asana Math} takes a lot of resource and is not suitable for very frequent changes of fonts.
