User Haider.Kiara on PS3Gameroom has a mission to localize GTA V into Arabic. No, really. The image below is a work in progress on PS3 and shows Arabic font appearing in-game.
Not too shabby. The user is asking for helping hands for anyone who is good in both Arabic and English to participate and help out. "The bigger the team, the faster we'll be able to translate this game." according to him. Let's hope this comes to fruition. Perhaps it'll be easier to mod the fonts once the PC version arrives this fall.
