Lua scripts are not loaded if there are non-Latin characters in the username

[PalmtopTiger]

The problem occurs when there are non-Latin characters in AppData path.
Also, some lua scripts cannot save files to %AppData%\mpv folder even with portable_config. Works.

Important Information

• mpv git-640db1e
• Windows 7 SP1 x64
• Source of the mpv binary

Reproduction steps

• Create a folder with non-Latin characters. For example: C:\mpv\Настройки.
• Put some scripts in C:\mpv\Настройки\scripts folder.
• Open the console.
• Set MPV_HOME variable: set MPV_HOME=C:\mpv\Настройки.
• Launch mpv.

Expected behavior

Scripts loaded

Actual behavior

Lua error: cannot open C:\Users\Андрей\AppData\Roaming\mpv/scripts/autoload.lua: No such file or directory

Yes, that's because we let Lua open the file. Windows is an absolutely braindead piece of shit, so you need extra hacks to even open a file that has non-ASCII parts in its name or path, and Lua didn't implement these hacks.

Is it possible to fix this?

AppData seems to work fine in Lua with portable_config. My mistake.

I found a workaround - setting MPV_HOME to a DOS path, for example: C:\Users\A4F7~1\AppData\Roaming\mpv.

Probably trivial to fix, someone just has to do it.

PS: and at least half the cursing goes to MinGW and their shitmess too, because they force EVERYONE to reimplement wrappers for open/fopen and any other standard C functions which take filenames.

#4903 #6424 and might be even more.

This particular issue is probably solved now, but Lua filesystem functions in general are not affected by this change.
