Because of that,>>> x=[u'1','aäöü']>>> x.sort()Traceback (most recent call last): File "<stdin>", line 1, in ?UnicodeError: UTF-8 decoding error: invalid datafails. As always in cmp, I'd expect to get a consistent outcome here(ie. cmp should give a total order on objects).OTOH, I'm not so sure why cmp between plain and unicode strings needsto perform UTF-8 conversion? IOW, why is it desirable that>>> 'a' == u'a'1Anyway, I'm not objecting to that outcome - I only think that, to getcmp consistent, it may be necessary to drop this result. If it is notnecessary, the better.Regards,Martin
