But then you're going to want an extended version of TFM files to 
support Unicode character codes, too, and we don't currently have that 
in XeTeX. Omega's OFM files would presumably do the job, but I haven't 
looked into supporting them. And I think there are issues with 
extending mathchar access to use Unicode character codes as well.

Aside from those issues, it's mainly a big, tedious job of updating 
*all* the fonts and files that people expect to find, so that all their 
legacy documents still produce the expected output.
