Missing support for accented characters

[alemercu]

I think gbarunner2 doesn't support è é à ù ò ì ç characters (maybe others but i tested with these), so when i launch a gba game in twilight menu with these characters (for example "pokémon emerald version.gba") gbarunner2 doesn't start the game but goes to the integrated file browser and the accented characters in file name aren't showed properly (for example "pok,mon emerald version.gba"). I know that i can still launch games in gbarunner2's file browser or simply change file name removing accented characters but if it's a fixable problem it would be much appreciated.

PS: I'm using gbarunner2 included in twilight menu v20.0.1

Every accented character has a different unknown character showed in gbarunner2's file browser, but some of them can't be written with a normal keyboard.
