>> Thanks, this bug is now fixed. But there is something wrong with the two diacritics (short vowels): ARABIC KASRA and ARABIC KASRATAN. They should appear UNDER the letters, not IN or OVER them.

>> Try a-A [Sheen-Kasra] or a-S [Sheen-Kasratan] or d-S [Ya-Kasratan].
>> But h-S or m-S has the correct form. (?)
