Such extensions of scope for different character types in Unicode vs. ASCII are a common gotcha when moving from Python 2 to 3. The same applies to eg. upper/lower case conversion, conversion to numeric values, the various .is*() methods, etc. > codecs.open() was advertised as a way of writing portable code for Python 2 > and 3, and it can still be used in many old programs. AFAIR, we changed this to recommend io.open() instead, after the io module was rewritten in C. Before that we did indeed advertise codecs.open() as a way to write code which produces Unicode in a similar way as io does in Python 3 (they were never fully identical, though). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue18291> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
