Nick Coghlan <ncogh...@gmail.com> added the comment: As Antoine said, there's a reason BaseException now implements both __str__ and __unicode__ and doesn't implement the latter in terms of the former - it's the only way to consistently support Unicode arguments that can't be encoded to an 8-bit ASCII string:
>>> str(Exception(u"\xc3\xa0")) Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128) >>> unicode(Exception(u"\xc3\xa0")) u'\xc3\xa0' For some of the exception subclasses that will always return ASCII (e.g. KeyError, which calls repr() on its arguments) then defining __unicode__ in terms of __str__ as Ezio suggests will work. For others (as happened with BaseException itself), the __unicode__ method will need to be a reimplementation that avoids trying to encode potentially non-ASCII characters into an 8-bit ASCII string. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6108> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
