It just occurred to me that this is similar to what packages like
siunitx do to get virgule decimal points instead of periods. There's a
package somewhere (the name completely escapes me) that does this
automatically in maths. Any of these approaches should be easily
customisable to use a unicode character in XeTeX instead of a plain
comma.

Hope this helps...
