Thanks.  It looks very interesting!

Can you tell me how to identify the characters with strong right to
left property?  (This not urgend at all.)

Currently I do the following, which doesn't cover the charset
mule-unicode-0100-24ff.

    (let ((charsets '(arabic-iso8859-6
                      arabic-digit
                      arabic-1-column
                      arabic-2-column)))
      (while charsets
        (modify-category-entry (make-char (car charsets))
                               bidi-category-r table)
        (setq charsets (cdr charsets))))

What I probably need is a string with all the characters in it which
have the right to left property.  Would that be feasible?

Something like the following for hebrew:

    (mapcar (lambda (char)
              (modify-category-entry char bidi-category-r table))
            "אבגדהוזחטיךכלםמןנסעףפץצקרשת")))
