If you're interested in APL, I'd suggest checking out J (http://jsoftware.com/ http://jsoftware.com/), a modern and free (though not open source) dialect, which only uses ascii. _J for C Programmers_ is pretty good. K, another APL dialect, is also quite amazing, but less free than J. (It's most recent version is called Q.) I don't know Farsi or Arabic, though. I studied Spanish and German in college, but majored in history rather than linguistics.
