[Windows] FDS games don't start if system path contains a special character

[bslenul]

Hey!

If the disksys.rom file is in a path that contains a special character, FDS games will fail to boot on Windows.
As a test I moved the BIOS in a "é" folder on my desktop and changed Settings > Directory > System/BIOS path in RetroArch:

[INFO] [Environ]: SYSTEM_DIRECTORY: "C:\Users\B-S\Desktop\é".
[INFO] [Environ]: GET_SAVE_DIRECTORY.
[INFO] [Environ]: SET_PIXEL_FORMAT: XRGB8888.
[INFO] [Environ]: SET_GEOMETRY: 256x240, aspect: 1.219.

[libretro INFO] File CRC32: 0x1F22CCB1
[libretro INFO] [Error] Could not load file: Zelda no Densetsu - The Hyrule Fantasy (Japan).fds

Full log: retroarch_mesen.log
It works fine on my Linux Mint VM however.

If you're in linux, try to start retroarch with the environment variable 'LC_ALL=en_GB.UTF-8'
as in

LC_ALL=en_GB.UTF-8 retroarch

Just a idea for a workaround that might not work. I'm unsure it would have any influence in a C application, as opposed to paths passed into it from the shell or output into a shell. Probably won't do anything.
