This would aldo require XeTeX to handle Unicode code points in math
fonts, by extending \mathchar, in the same way as it does for text
fonts by extending \char.
A temporary workaround has been initiated by Will Robertson's xmaths
package <http://www.mecheng.adelaide.edu.au/~will/>. I've installed
it but I haven't had time to test it really. The only thing I've
noticed is that, apparently, omitting the braces with single letter
subscripts and superscripts doesn't work any longer, whereas it works
in LaTeX. Namely, for example, $a_\mathrm{h}$ which works in LaTeX
doesn't work with xmaths.sty loaded; I suspect it needs to be coded
in the more correct way as $a_{\mathrm{h}}$. Probably a macro
expansion problem.
