Actually, that does not mean I think it is a good idea. The
conceptual problem is that \XeTeXmathcodenum (and therefore
also \Umathcodenum) can return a signed int to represent an
unsigned value, with is pretty horrible.

Why is it so important to be able to do a mathcharnumdef
(instead of a macro definition or straight \Umathchardef?)
