STINNER Victor added the comment:
It looks like the wide character strings (wchar_t*) are misused. For example:
error(RC_NO_PYTHON, L"Requested Python version (%s) ...", &p[1]);
fwprintf(stdout, L"usage: %s ...\n\n", argv[0]);
The %s formatter is for byte string (char*), "%ls" should be used instead.
+ _setmode(_fileno(stdout), _O_WTEXT);
Extract of wprintf() documentation:
"The wprintf() and vwprintf() functions perform wide-character output to
stdout. stdout must not be byte oriented; see fwide(3) for more
information."
So _setmode() or fwide() should be used if I understood correctly. Or wprintf()
should be replaced with printf() (still with "%ls" format)?
wprintf("%ls") replaces unencodable character string arguments by ? (U+003F),
whereas printf("%ls") and wprintf("%s") truncates the output at the first
undecodable/unencodable character:

So wprintf() is probably better here.
