Launchbox not working with Retroarch with some folder names

[Iker]

After many tests, Launchbox does not start the games added with the RetroArch emulator if the roms and the Retroarch emulator and the Launchbox frontend are inside a folder whose name has a Spanish accent, such as "Emulación". If you changes the name to "Emulacion", Launchbox starts the game without problem.

If instead of using Retroarch you add another emulator, such as Project64, the games will work, whether the parent folder is "Emulación" or "Emulacion".

This happens both with the programs in Spanish and in English.

Thank you!
