    I was not well and forgot to check all the code supplements too: I wondered--with all the other forms of aleph available as either a composite or a single character,
    why is this one of the aleph glyphs, the aleph with the double fatah diacritic (for the accusative indefinite at word end)
    not available except as a composite character?

    But then I found the code point:


    in presentation forms-A; my mistake--it is there, as a presentation form.

    (The aleph glyphs with hamzas and long vowel diacritics, unlike the aleph glyphs with short vowel diacritics and no hamza are in both the basic Arabic characters and in presentation forms-B as well;

    but the aleph glyphs with short vowel diacritics are only in the presentation forms;
    I guess that this is intentional and not an oversite.)


    However, first, both character orders must result in a display which orders the diacritic before (that is to the right of, because Arabic script normally displays as rtl) the aleph.

    They both do; so this is fine.


    Second, and the real problem here may have something to do with implementation and not with unicode at all: the spacing between the diacritic and the aleph varies according to the logical order of these two
    (which as far as I know is really just a stylistic variation in Arabic;
    at least this variation in spacing occurs with IE; try it with other browsers and see what happens; I redid the attached example so you can see the presentation form too.)

    Hi, I am not a native speaker of Arabic by any means; I can just barely read some in it; perhaps native speakers can help me with this.

    You have all the variant glyphs of each character catalogued under a single character
    for the most part
    however there are various forms for Arabic aleph I presume because it is impossible to guess what vowel property it is associated with.
    Also, in my opinion, which may not be correct, ا not آ should be the base character in this group--the squiggle across the top of ɮ is a long vowel mark; an option, in fact, would be to insert all voweling across a character like ا as diacritic marks; in fact, to create the accusative indefinite aleph at the end of a word it is necessary to use combined characters (ًا) although the order is somewhat unimportant except for spacing between the characters--which makes no sense either as the spacing is irrelevant. (See attached file.)
    (Back to my beginning comment, I still wonder why the differential treatment of the various aleph glyphs, with some elevated to a sort of character status and others not--but it's not so important to answer this as the other comment.)
