xadvance issue in Persian/Arabic (RTL)language

[Younes Mashayekhi]

First thank u for correct miss characters in charset.txt for RTL languages
but as you see in this picture now we have a problem with xoffset like اییی or اششش or اططط
is there any way to set xoffset to correct this problem ?

I'm happy that the latest fix solved a tiny piece of RTL problems for you.
The real problem is Opentype.js module which I heavily relied on lack of support for RTL languages, and I myself is having poor knowledge on that too. So it might won't be fixed soon.

I'm considering switching from Opentype.js to fontkit which does excellent on RTL languages. That's a lot of works.
