I don't have a font installed which will print
those characters.  When I load your sample file,
I see print statements which include unicode
characters like \u5341.  The printed output
contains the same unicode characters as the
input program.  Maybe Martin has an idea.

I've attached an example file to demonstrate the problem 
better.

it seems not to be the length but something else which I 
haven't figured out yet.

I've also added the encoding comment and also tried 
changing the default encoding in sitecustomize.py from latin
-1 to utf-8 but neither seem to work.

thanks,

James.

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
