STINNER Victor <victor.stinner at haypocalc.com> added the comment:

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.
