[New-bugs-announce] [issue33928] _Py_DecodeUTF8Ex() creates surrogate pairs on Windows

[STINNER Victor]

New submission from STINNER Victor <vstinner at redhat.com>:

_Py_DecodeUTF8Ex() creates surrogate pairs with 16-bit wchar_t (on Windows), whereas input bytes should be escaped. I'm quite sure that it's a bug.
