Bug#653125: Farsi characters problem

[Sasan Rose <sasan.rose@gmail.com>]

Package: debian-i18n
Severity: grave
Tags: l10n
Justification: renders package unusable

Dear Maintainer,
Farsi layout is working system wide without any problem, but using 
terminal or vim or gvim, farsi characters are just bunch of question marks.
I tried to change terminal profile's font but no success. Even no 
success with BiCON. I reconfigured locale package and even tried to set 
some env.
Here is my locale output:

LANG=fa_IR:fa
LANGUAGE=en_US:en
LC_CTYPE="fa_IR:fa"
LC_NUMERIC="fa_IR:fa"
LC_TIME="fa_IR:fa"
LC_COLLATE="fa_IR:fa"
LC_MONETARY="fa_IR:fa"
LC_MESSAGES="fa_IR:fa"
LC_PAPER="fa_IR:fa"
LC_NAME="fa_IR:fa"
LC_ADDRESS="fa_IR:fa"
LC_TELEPHONE="fa_IR:fa"
LC_MEASUREMENT="fa_IR:fa"
LC_IDENTIFICATION="fa_IR:fa"
LC_ALL=fa_IR:fa

As I told not all the applications are affected for example gedit is 
working fine, but the annoying part happens when I want to use services 
that are run from terminal.
For example kannel. When I call the api and send a Farsi string, it 
receives all of them as question marks and send sms as just bunch of 
question marks.
