I am fairly ignorant of unicode and encodings, but I am 
surprised you got anything coherent without an encoding 
cookie comment at the top (see manual).  Have you tried 
that?  Other questions that might help someone answer:

What specific XP version?  SP2 installed? Country version?
Your results for
>>> sys.getdefaultencoding()
'ascii'
>>> sys.getfilesystemencoding()
'mbcs'
What happens if you reverse the order of the print 
statements?  (Ie, is it really the shorter string that 
does not work or just the first?)

I don't know enough to know if this is really a bug.  If 
you don't get an answer here, you might try for more info 
on python-list/comp.lang.python
