But in this way I can resolve only one of the four different presentation forms. In this specific example of "ve" I have two different presentation forms, separate form (UFBDE)and last-joining form(UFBDF). My question is: how to implement this letter same like as, for example, "Arabic_beh" so that I can resolve all the existing forms with one key and it changes from one form to the other according to the previous and next letter in the word as I type.
