Interesting. Here is what I get:
 >>> import locale, string
 >>> locale.getlocale()
(None, None)
 >>> string.uppercase

Somehow the locale for your system has changed from the 'C' locale. If I 
set the default locale I get similar results to yours:
 >>> locale.setlocale(locale.LC_ALL, '')
'English_United States.1252'
 >>> locale.getlocale()
('English_United States', '1252')
 >>> print string.uppercase

which doesn't print correctly because my console encoding is actually 
cp437 not cp1252.

It looks like string.uppercase is giving you all the characters which 
are uppercase in the current encoding, which seems reasonable. You can 
use string.ascii_uppercase if you want just A-Z.
