Ligature and Mark position

Post by Husham »

Hello,
I Would like to talk about some issue occur with Arabic ligature (lamalef-arab) there is more than 8 type, i will take one of them as example: this compose of ("lam-arab.init" and "alef-arab.fina" to compose "lamalef-arab.isol"). every thing is O.K when I position marks with open type feature window, BUT when it comes to test and put the marks it will decompose to its components (lam-arab.init and alef-arab.fina), the normal situation must be like figure 2 (Arial)

The marks must not be processed to form the ligature:
