Андрей Баксаляр added the comment: A same problem with the unicode case mapping is still present in the Python 3.4.3. You can repeat the bug with this code, for instance:
'ΰ'.upper().lower() == 'ΰ' The case swapping is strangelly leads to character replacement: b'\xce\xb0' → b'\xcf\x85\xcc\x88\xcc\x81' ---------- nosy: +Андрей Баксаляр versions: +Python 3.4 -Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12736> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
