Joined forms of Persian letters in Emacs

[Masood Ghayoomi]

Dear All,

I installed the latest version of Emacs (24.1.1) which supports bidirectional texts.
I can type Persian letters, including the 4 letters which do not exist in Arabic, and do the typing right-to-left.
The problem is that all the letters are in written in *dis-joined* form which is not an appropriate display for Persian words.
Eg: گفت is displayed as گ‌ف‌ت
Any idea how to fix it?

Best regards,
Masood Ghayoomi

Salaam Massood,

The default fonts that gets selected by emacs in
your environment, do not properly support shaping.

Try invoking emacs with:
/usr/local/bin/emacs -fn 'Monospace 12'

Or from the Menu: Options -> Set Default Font.

Please let me know if that solves the
problem. Thanks.

I am the author of persian.el -- Emacs 24's
Persian Input Methods.

See:

Persian Input Methods
For Emacs And More Broadly Speaking
شیوه‌هایِ درج به فارسی‌
http://www.persoarabic.org/PLPC/120036

for details. For cover to cover reading the pdf
format is better.

In addition to farsi-isiri-9147, Emacs supports a
Multi-Character (Reverse) Transliteration Persian
Input Method called: farsi-transliterate-banan.
It makes the latin keyboard an intuitive
transliteration input method for persian.

Have you tried that? --
M-x set-input-method farsi-transliterate-banan

I'd love to get more feedback on
farsi-transliterate-banan input method from fresh
users. Just read the "Short Description" on the
access page
http://www.persoarabic.org/PLPC/120036
and start using it.

The latest version of emacs on the development
trunk has Persian as a language also added to the
language menus.

Indeed, emacs is now the most powerfull and
complete user environment for perso-arabic. Far
surpassing all proprietary software.

I'll be making proper announcements for these
soon.

ارادتمند،

...محسن

I have captured a description of that problem and
possible causes and solutions in:

Shortly after this note, I'll also send out
additional information about
PersoArabic With Emacs
and

Font-shaping was still not working correctly for me using the 2013-03-11 default build of emacs for OS X. There was an issue filed in the build-emacs project about Persian/Arabic font-shaping. The suggested fix is to use a nightly build later than 2013-09-15. I tried out the 2014-05-31 nightly release and font-shaping works correctly using a monospace font and M-x set-input-method RET farsi-transliterate-banan.

Yet one more reason to love emacs.

Salaam,

Here are some guesses:

1) The m17n/m17n-dev library may be missing on
your raspberrypi. You need that for shaping.

2) The font being used is not capable of being
properly shaped.

Is this a problem that you are only seeing on RPi
or are you seeing this problem on all linux
platforms?

Best,

...Mohsen

Wasalam.

Thankyou so much for taking the time to look into my query. Please find my answers below

  1) The m17n/m17n-dev library may be missing on
  your raspberrypi. You need that for shaping.

 

I installed libm17n-dev – library, as suggested, still the appearance is same, "disconnected characters".

 

  2) The font being used is not capable of being

  properly shaped.  ---

 

I tried ARIAL Unicode, MS Serif Font, as well as FARSI fonts from http://alefba.us/free-arabic-persian-farsi-urdu-kurdish-fonts/

And also changed the locale to “GB_GB ISO-8859-1 and GB_GB ISO-8859-15”..... still no change in display.   

3)  Is this a problem that you are only seeing on RPi

or are you seeing this problem on all linux 

platforms?  --  

Issue is only in RPi.  That too, only when displayed through C# application. Same label when displayed through java application works perfectly fine. And text editor also works fine.

Further i installed “https://github.com/behdad/bicon” bicon library, still the issue remains. 

Is there something else i should try, is there any other cross compiler to display persian characters in a RPi on linux box. 

Appreciate your valuable suggestions/inputs.

Thank you,
