Problem in arabic script

Problem in arabic script

[Mehdi Omidali]

I use context+luatex to write farsi texts. A problem that I have been
faced is that some characters (those that are in farsi and not in
arabic like "Gaf", "Kaf", "Ya" and "Che") are shown only in isolated
form. How can I solve this problem. I use ubuntu and latest context
and luatex.
Thanks

Hi Mehdi,

what font are you using? Have you tried with a different font?

Please send me -- off list -- a small sample file with the font, and I'll  
examine it.

Best wishes

Hi Burak,
I almost used any font from ubuntu, Microsoft, and Mac, but the
problem is the same for all of them. As an example please see
http://www.omidali.com/test.rar
in which I have included the source file and the output. I have used 3
different fonts, namely, Arabic Transparent and Time New Roman from
windows, and SimplifiedNaskh which I found in a thread by Idris.
Thanks.

Dear Idris
سلام
I tested many fonts, like Sil's Scheherezade and Lateef, farsiweb fonts
http://www.farsiweb.ir/font/farsifonts-0.4.zip
(roya for example), Mac X series which you can find one of them from
http://irmug.org/portal/index.php?name=Downloads&req=getit&lid=30

A sample file with the output and also 3 fonts that have been used is in
http://www.omidali.com/test.rar

Best regards,
Mehdi

I have added support for farsi in font-otf.lua. Ultimately we need to add  
all unicode chars that submit to contextual analysis, like Urdu, Pashto  
etc.

Until Hans gets back, do the following:

open font-otf.lua

go to line 4660

replace that definition with this one:

     local isol_fina_medi_init = {
         [0x0626] = true, [0x0628] = true, [0x0629] = true, [0x062A] =  
true, [0x062B] = true, [0x062C] = true, [0x062D] = true, [0x062E] = true,
         [0x0633] = true, [0x0634] = true, [0x0635] = true, [0x0636] =  
true, [0x0637] = true, [0x0638] = true, [0x0639] = true, [0x063A] = true,
         [0x0640] = true, -- tadwil
         [0x0641] = true, [0x0642] = true, [0x0643] = true, [0x0644] =  
true, [0x0645] = true, [0x0646] = true, [0x0647] = true, [0x0649] = true,  
[0x064A] = true,
         [0x067E] = true, [0x0686] = true, [0x0698] = true, [0x06A9] =  
true, [0x06AF] = true, [0x06CC] = true,
         [zwj] = true,
     }

save and regenerate the format.

try your file again. Works here.

Note that artro.ttf does not seem to have the correct opentype info for  
06CC, so it's not processed correctly.

Best wishes
Idris
