Math fonts vary greatly in their coverage and there is no clear cut what a math
symbol and what is not. I don’t know if MathClass-XX.txt is used in anything in
practice, but I guess we can make an orthography file out of it and test it
with the existing math fonts, possibly reducing it until we get them all
covering math.
