Re: Problem Using Persian Fonts

["Ali Majdzadeh" <ali majdzadeh gmail com>]

Hi Behdad
I think I solved the problem, my test program ran correctly and I was
able to change fonts. I think the problem was about the configuration
of installed fonts.
Thanks a lot anyway

Regards
Ali

Hi Behdad
Thanks for your response.
You are right. But I am new to Pango and Gtk+ and I could not find any tutorial explaining a sample test program that utilizes Pango's font-related APIs.
Can you explain the procedure (specifically for Persian)?
I have installed a series of standard Persian fonts which I think Mr.Pournader have
published. Other programs like OpenOffice work well.

Didn't you send this already?  I think anyone would have replied
the first time if they had something to add.  With the
information you give in your problem report (or lack thereof), I
don't think anybody can help you.  You have not even attached
your complete test program with the Persian text.
