This was a parser bug in mathtext which is fixed in CVS. Be sure and
let me know when you encounter these kinds of problems since they are
usually easy to fix
While I was at it, I also implemented unicode support for the *Agg and
PS backends 
If you have access to CVS, you may want to give it a
test drive. See examples/unicode_demo.py. CVS mirrors may lag.
