[Python-Dev] Suggested PySys_SetArgv use with a (char **) argv ?

[Campbell Barton]

The reason I was a big vague is that I'm not really bothered HOW its
done, I'd just like there to be some way to use PySys_SetArgv with a
(char **)

Definitely not suggesting that PySys_SetArgv be reverted to the way it
worked in py2.x, if there was 2 versions of PySys_SetArgv that would
be acceptable to me. PySys_SetArgvASCII() maybe?

Alternately a function to convert the char **argv to wchar_t **argv
could be ok too.

PyOS_char2wchar would be useful though it still means you need to
manually copy the argv, convert and free it.
