Originally Python exceptions had no __unicode__ method. In Python 2.5
__unicode__ was added. This led to "unicode(Exception)" failing and so
the addition of __unicode__ was reverted [1].
This leaves Python 2.6 in a position where calls to
"unicode(Exception(u'\xe1'))" fail as they are equivalent to
"uncode(str(Exception(u'\xe1'))" which cannot convert the non-ASCII
character to ASCII (or other default encoding) [2].
From here there are 3 options:
1) Leave things as they are.
2) Add back __unicode__ and have "unicode(Exception)" fail.
3) Add a tp_unicode slot to Python objects and have everything work
(at the cost of adding the slot).
4) Fix PyObject_Unicode to not retrieve __unicode__ from new-style
instances, and instead only look for the method on their types (similar
to the way PyObject_Format looks up the __format__ method).
Cheers,
Nick.
