In this case, it will be better to raise an error on non-ascii byte (character) in the format string. It's better to raise an error than to interpret utf-8 as iso-8859-1 (mojibake!). Since nobody noticed this bug (PyFormat_FromString/PyErr_Format expects ISO-8859-1), I suppose that nobody uses non-ASCII format string is always ascii. Python builtin errors are not localised. If an application uses gettext, I suppose that the error will be raised in the Python code, not in the C API. Attached patch changes PyFormat_FromStringV (and so PyFormat_FromString and PyErr_Format) to reject non-ascii byte (character) in the format string. I added a test and documented the format string encoding (which is now ASCII). See also #9738 for the documentation about function argument encoding. ---------- keywords: +patch Added file: http://bugs.python.org/file18800/pyunicode_fromformat_ascii.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9769> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
