I used some methods to decode my content to the unicode and I could display  all of content to the Farsi.

I am unable to display content by a non true  type font
As I told before, I could display every thing with any true type  font!

I just have problem  to non true type fonts, because iText can not resolve "Identify-H" for non true type fonts  in jasper report project!

I just need to the Nazanin True Type font, if anyone so, please send it to me.
