ASCII and UTF-8 are the two most common codecs in the world, so it's justified to have heavily optimized encoders and decoders. I don't know any application using UTF-32-LE or UTF-32-BE. So I don't want to waste Python memory/code size with a heavily optimized decoder. The patch A looks to be enough. -- 32 bit units is commonly used with wchar_t, but this format already has a fast decoder, PyUnicode_FromWideChar(), which uses memcpy() or _PyUnicode_CONVERT_BYTES(). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14625> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
