> _PyUnicode_FromASCII(s, len) is faster than PyUnicode_FromString(s) because > PyUnicode_FromString() uses temporary _PyUnicodeWriter to support UTF-8. I don't understand how _PyUnicodeWriter could be slow. It does not overallocate by default. It's just wrapper to implement efficient memory management. > Oh, wait. Why we used _PyUnicodeWriter here? To optimize decoding errors: the error handler can use replacement string longer than 1 character. Overallocation is used in this case. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37348> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
