I've got the following problem, in python 2.1, 2.2 and
2.3a0 (Debian):

>>> import re
>>> re.compile(r'\w+', re.U).sub('X', u'hello caf\xe9')
u'X X'
>>> re.compile(r'\w{1}', re.U).sub('X', u'hello caf\xe9')
u'XXXXX XXXX'
>>> re.compile(r'\w', re.U).sub('X', u'hello caf\xe9')
u'XXXXX XXX\xe9'

The first two results are ok, but the third is not.

I just posted a small patch to sre_compile.py which should fix this:

Fixed in 2.3 CVS using Greg's patch. Will backport to 2.2 as
well.
