New version of the patch _Py_wchar2char-2.patch: - _Py_wchar2char() only escapes characters in range U+DC80..U+DCFF (instead of U+DC00..U+DCFF) - add a comment to _Py_char2wchar() > I don't understand why you decrement `size` in the second pass. Because I would like to avoid buffer overflow when calling wcstombs(). wcstombs() might write more bytes at the second step, even if I don't think that it would be possible.
