You should ensure that loaded bytes are ASCII-only. Otherwise broken or malicious marshalled data will compromise you program. Decoding UTF-8 is so fast as decoding ASCII (with checks) and is almost so fast as memcpy. As for output, we could use cached UTF-8 representation of string (always exists for ASCII only strings) before calling PyUnicode_AsUTF8String(). I'm good with buffering and codes for short strings and tuples (I have not examined a code closely yet), but special casing ASCII looks not so good to me. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19219> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
