This allows you to open filenames that fits local codepage. But you can not
open filenames within French characters on Russian Windows and vice-versa.

Original patch allows you to push (almost) any Unicode filenames (converted
to UTF-8) to avformat_open_input() as well as in local codepage
(UTF-8 name interpretation will be in priority if both files exists though
I have no idea is it possible at all).

Notice that though in Windows command line console you can not see all
Unicode characters at-once they are pushed right on copy-paste
(means you can see wrong filename in console and still open file correctly
because internal storage is UTF-16).
