of course.

and if all you do with the result is write it to an UTF-8 stream, it 
doesn't need to be done at all.  this requires a slightly more elaborate 
C-level API interface than today's PyString_AS_STRING API, though...

(which is why this whole exercise belongs on the Python 3000 lists, not 
on python-dev for 2.X)
