Hi,

I'm experiencing strange behavior with attached code, that differs depending 
on sys.setdefaultencoding being set or not. If it is set, the code works as 
expected, if not - what should be the usual case - the code fails with some 
non-sensible traceback.

I tried to boil it down to a comprehensible state, but some LOC are still 
involved. I use similar code to represent database records, where the repr's 
appear in user visible logs for example.

It is greatly appreciated, if some kind soul could shed some light on this 
ungrateful behavior.

Thanks in advance,
Pete
