I'd suggest to look into the Unicode character database (the file
UnicodeData.txt on the Unicode site).  Each character there is
classified for the bidi algorithm already.

If all the Arabic characters have the same category, you can use the
feature of char-tables where setting a single entry for the generic
character has the effect of setting it for the entire charset.  (I
thought that's why you've chosen category tables as the implementation
for this; I know that's why I suggested to use char-tables.)
