I'm not sure this is related only to PEP 3131 changes (I haven't  
tried it yet), but I hit a similar problem when I was working on the  
email package.  I think I posted a message about it in a separate  
thread.

If an exception gets raised with a message containing characters that  
can't be printed on your terminal, you get a nasty exception inside  
io, which obscures the real exception.  The resulting traceback makes  
it difficult to debug what's going on.  I haven't looked deeper but / 
my/ solution was to repr the message before instantiating the  
exception.  IWBNI Python itself Did Something Better.
