Query: Problem of Multiple Diacritics Design for Arabic Script   This study focuses on the design of multiple Arabic diacritical marks and to
developing a model that generates the stacking of multiples Arabic diacritics
in order to integrate it into a system of Arabic composition. The problem
concerns the presence of multiple diacritics on a single basic letter. This
model is based on the layering composition. The combination of diacritics with
letters requires a basic layering to combine any diacritics in the word with
their base letter, without having to deal individually and separately each pair
of base letter and diacritics.
