Actually, it is not. In Py3k, x.encode() always requires x to be a str (i.e. unicode) instance and return a bytes instance. y.decode() requires y to be a bytes instance and returns a str (i.e. unicode) instance. > I think you have to ask another question: Is repr() allowed to > return a string (instead of Unicode) in Py3k ? In Py3k, "strings" *are* unicode. The str data type is Unicode. If you're asking about repr() possibly returning a bytes instance, definitely not. > If not, then unicode_repr() will have to check the return value of > the codec and convert it back to Unicode as necessary.

Atsuo's PEP has now been checked in as PEP 3138. Discussion should start soon on the python-3000 list. __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue2630> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
