Don't know much about the Arabic family of fonts but I use the greek and hebrew fonts for the biblical language program, Accordance. I've used many similar programs on the pc side but all of them had really, really crappy font mapping. On the mac it is really easy. The final Mem and nun (hebrew) and final sigma (grk) are added automatically at the end of words. Combination accents, (like a rough breathing mark and a circumflex over the selected vowel) only require 2 keystrokes as opposed to the 8 1/2 fingers needed to do the same thing on the PC side. Iota subscripts only require an 'option-j' after the vowel. This doesn't help much with your Arabic font problem, but maybe it'll help you to know that there are fonts for the mac and they do work well.
