Thanks. Much better now :-)
I also checked the diacritics (tashkil): It seems that they do not take up column number in Emacs.
In gedit, cursor movement is similar, but the vowels there do take up column number (as for cursor movement, as in emacs: forwards/backwards skips them, while 'delete' handles them separately). I find this behavior more consistent with the way both programs handle the lam-alef ligature (one cursor-movement space, but two column numbers).
However, as I said, I do not know which behavior is the most natural for Arabic users.
Checking the *Hebrew* diacritics (nikkud), I noticed a problem:
In some cases the diacritics are displayed in the wrong position (their "real" cursor position is correct, which makes the UI *very* confusing). e.g. if you type " עָלֵינוּ" , the Qamatz (first vowel) appears under the space instead of under the Ain (first letter). If you remove the space, the Qamatz does not appear at all. The Zeire (second vowel) appears under the Ain (first vowel) instead of the Lamed (second letter). However, the Shuruk sticks to the Vav (last letter) as it should (though the positioning is too close and to high IMHO).
I do not know if this issue is specific to my build.
