[ CORE ] FFNX can't read from paths with unusual characters in them.

[zaphod77]

Describe the bug

Steam versions use the Documents directory to store saves and other configuration information. This directory cannot be moved or renamed. If the username has a character that's more than 8 bits, FFNX can't read anything from a path containing it.

To Reproduce
Steps to reproduce the behavior:

1. Have a local username with a >8 bit character in it that is in the user's home directory in c:\users\ .
2. Install Steam FF7 or FF8.
3. Run it once.
4. extract FFNX to installation
5. Run the game exe
6. FF7_en.exe immediately crashes with an unhandled exception because it can't read metadata.xml and doesn't even check for this case, just as if you've never ran it on steam. Because there is no exception handler, nothing even gets logged past [TRACE]Metadata: Initializing manager.

Expected behavior
The game starting.

GPU

Irrelevant, the crash has nothing to do with graphics.

Additional context
This was a real pain to track down, because there is no exception handler for this particular case. And users can't simply rename their home directory to work around it, so at the very least an exception handler should be placed it to reveal this happening, so the user can create a symlink to what FFNX thinks the path is.
