Re: Arabic Shaping Patch

[Isam Bayazidi <bayazidi at arabeyes dot org>]

Hi Helge, 
  It seems that ligatures really describe what I need .. Now is there some 
ready made functions in LyX for those replacements ? are they used in LyX in 
the first place ? Do I have to create the replacement functions ? or use some 
existing ones ?
  Thank you Helge for helping me with the word ligatures as it exactly 
describe what I need ..
  
  One little note .. you said:  
>Well, perhaps it is necessary

Well the replacements I am talking about are necessary for Printing as well, 
as it improved readability in screen or paper.. it improves readability in a 
way that not using it would be unaccepted..

Yours
