[New-bugs-announce] [issue10780] Fix filename encoding in PyErr_SetFromWindowsErrWithFilename() (and PyErr_SetExcFromWindowsErrWithFilename())

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

PyErr_SetFromWindowsErrWithFilename() expects a filename encoded to UTF-8. It is called by win32_error() function of the nt (posix) module, and win32_error() is called on an error in the bytes implementation of a function (if the argument is a byte string, not an Unicode string). But on Windows, bytes filenames are encoded to the ANSI code page, not to UTF-8.

PyErr_SetExcFromWindowsErrWithFilename() expects also a filename encoded to UTF-8. It is not used in Python core, but I think that it should be fixed too.

See also #10779 (and #9713 and #10114).
