The warning should also explain how to get backwards-compatible behaviour, i.e. suggest encoding="locale". Inada Naoki <[email protected]> wrote: > This warning is opt-in warning like BytesWarning. What use is a warning that no-one sees? When the default is switched to encoding="utf8", it will break software, and people need to be warned of that. UnicodeDecodeError's will abound when files that used to be read in a single-byte encoding fails to decode as utf-8. All it takes is a single é. If the default encoding is ever to change, there's no way around a noisy warning. How about swapping around "locale" and None? That is, make "locale" the new default that emits a warning, and encoding=None emits no warning. That has the advantage that old code can be updated to say encoding=None, and then it will work on both old and new Pythons without warning. regards, Anders _______________________________________________ Python-Dev mailing list -- [email protected] To unsubscribe send an email to [email protected] https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/[email protected]/message/GZOHZAXKJDRJPF32U2ET5E32SOYXHR5E/ Code of Conduct: http://python.org/psf/codeofconduct/
