Speaking as a Semitist -- not in IT person -- this is no problem.
The vowel signs sit in Arabic above (or under) the consonnant.
sukun, the no-vowel-sign, sits above.
But in the data stream -- both IT wise and while reading or writing --
it comes after the consonnat.
i guess "aw°" is perceived as equivalent with "aẘ"
both stand for اوْ
