Summary	0000620: The \Umathcharnumdef primitive
Description	XeTeX has the \XeTeXmathcharnumdef with obvious semantics as a complement to \XeTeXmathchardef and the other math…num commands. The attached patch implements this primitive for LuaTeX. The \Umathcharnumdef primitive is useful for e.g. \Umathcharnumdef\foo=\Umathcodenum `a
