While the Parker Brothers version is with Romanized characters, implying that Ouija can be used with any language capable of being romanized, we can infer that the game can be modified to accomodate any language based on an alphabet or syllabary. Build your own Ouija board with Arabic script, improvise a platen, and test this yourself. It will work. I know this because I built my own Ouija many years ago; you don't need to buy the branded game.
