Funny, I think me, linuxz and oomlx had a talk about it at #arabeyes.

Any fruits? :)
There has been a paper published outlining some nice methods for arabic OCR, 
That should help I assume.

but the math of it is just beyond me.


Heh, really? you should consider expanding your horizons (or brains) :P :P

here is the paper:

    As mentioned earlier

    It may be worthwhile and faster if Arabic support is implemented into
    Tesseract-ocr ..

    The important thing is the support of unicode.. tesseract 2.0
    http://code.google.com/p/tesseract-ocr/ can use and understand unicode
    and could be trained for any language that don't have its characters
    joined..

    What it is lacking is mentioned in the training page :

    I did a very very simple test :
    http://groups.google.com/group/tesseract-ocr/browse_thread/thread/b1b27838c68681ab

    If you could help, please please do so.

    Note:- As far as I know, right now..there is NO working Arabic-capable
    OCR engine.. free or otherwise.. I doubt if Sahkr software can detect
    anything.
