Hi,
I think, there may some problem in caseless matching, it may or may not be a 
valid match using the full casefolding, but here it also matches in V0:

>>> regex.findall(ur"(?V1i)K", u"\N{KELVIN SIGN}")
[u'\u212a']
>>> regex.findall(ur"(?V1)K", u"\N{KELVIN SIGN}")
[]
>>> regex.findall(ur"(?V0i)K", u"\N{KELVIN SIGN}")
[u'\u212a']
>>> regex.findall(ur"(?V0)K", u"\N{KELVIN SIGN}")
[]
>>> 

I am not sure, whether there might be some other characters with such behaviour.
