Hi, every one.

I work on arabic font, and apply "kern" feature. It work properly With following characters:

   REH_isolated (ر) + ARABIC COMMA (ØŒ)

   REH_isolated (ر) + ARABIC QUESTION MARK (ØŸ)

 

 

Because It doesn't work with following characters:

Uniscribe breaks characters into sequences, so each of them will be shaped by particular shaping engine, e.g. Arabic, Thai or Latn. So, if two characters do not end up in the same item they can't interact, e.g. ligated or kerned.

 

Arabic punctuation is considered Arabic character and so goes to the same item with Arabic letters, but generic punctuation amy or may not go with strong characters, depending on the input or flags passed to Uniscirbe.

 

Thanks,

Sergey

I remembered that MS Word ignore these kerning information.  Not sure if it is still true for the current version.
