My personal point on changing the default encoding of Python: don't do it 
(other people
will see this different).  As long as you are dealing with really only 
*one* encoding it
might be ok. As soon as you mix different encoding (which happens easily 
with utf8 and
iso-8859-X) you are doomed at some point within your application because 
you will never know
why it some string with some encoding converted to whatever. My strategy if 
you need unicode:
keep the default encoding as it is (ascii) and convert everything 
internally to Python unicode
string - not to utf8 encoded string. Perform every operation internally 
using unicode strings.
Only convert to utf8 on the presentation level (means when you send data 
back to the client
or export data to the filesystem or whatever). Such a clean separation 
between internal Unicode
representation and external representation saves you a lot of trouble.
