The following is from Idle3 (IDLE for Python3:

>>> 'this an example language ' + 'español'
'this an example language español'
>>> 

In Python3 all strings are unicode, so your problem just does 
not exist.  Upgrading to Python 3 would eliminate the problem, 
as the above extract demonstrates. 

Perhaps it is time to upgrade to Python 3.2 

In the above when I write Python 3, I mean "Python 3.1 or 
higher".  

With kind regards,

OldAl.

PS: I do not have Spanish on my computer, but I do have at least 
one other languages that uses characters that are outside of 
ascii limit of 128.
