New submission from Serhiy Storchaka: In most cases when str object required, unicode object is allowed too. "s" and "z" codes (with modifiers) in PyArg_Parse*() accept both str and unicode instances. But "c" code accepts only 1-character str, not unicode. This makes harder writing version-agnostic code with imported unicode_literals (2.7 functions require bytes literals, 3.x functions require unicode literals) and breaks pickle compatibility (see issue13566).
This change will affect: * str.ljust(), str.rjust() and str.center(); * '%c' % char; * mmap.write_byte(); * array constructor and item setter for 'c' type; * datetime.isoformat(); * bsddb.set_re_delim() and bsddb.set_re_pad(); * msvcrt.putch() and msvcrt.ungetch(); * swi.block.padstring(). ---------- components: Interpreter Core files: getargs_c_unicode.patch keywords: patch messages: 206529 nosy: alexandre.vassalotti, pitrou, serhiy.storchaka priority: normal severity: normal stage: patch review status: open title: Allow 1-character ASCII unicode where 1-character str is required versions: Python 2.7 Added file: http://bugs.python.org/file33193/getargs_c_unicode.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20015> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
