lol, not really a friend bought it from a store in israel, so i dont really know sorry. (but you really made me laugh)
Well, I am glad I brightened your day a little, at least.
I recommended that he use a GLCD, and so were others (apparently, someone even posted a link to a project for writing arabic on a GLCD - a font library rendering system of sorts). After your post, I then tried to look for "multilingual character LCDs" but didn't get far; it seems like you can only find english, japanese, and chinese displays on the mass market.
I am sure you can get others as well, but they would likely have to be a special OEM order kind of item (ie, order 1000+ direct from the manufacturer with a custom made character set on the CGROM). This is likely how your friend got the hebrew version; someone in israel likely sourced them special-made from a device manufacturer of LCDs with a custom hebrew character set on the ROM, and then they sell them to hobbyists and/or developers (that, or someone had done it for a device run, didn't make it in the market, and they landed on a surplus deal or something).
I know that Israel has a lot of "high-tech" industry (one company there, for instance, called Actuate - makes one heck of a nice reporting software package - it isn't cheap, though); I am not sure how much a place like, say, Saudi Arabia has - but that would be one of the few places that you likely could find such a device. Its such a niche item that only has wide usage and need in predominantly Arabic-speaking countries. I suppose for your hebrew LCD, it is likely only something found in a predominantly hebrew-speaking country, like Israel.
Lastly, I am not even sure if readable Arabic script could be fit into the dot patterns on a standard character LCD; the script is fairly ornate, and may or may not be reproduceable in a readable fashion, unless there is some simplified form which I am probably not aware of...
