Contains Screenshot, Font, Sample Source Code (gtkmm)

Hi gnome world,

there are some display problems in gnome applications with a special arabic font.
In LibreOffice there is no problem with the font, everything is right where it should be. Even on Windoze everything is fine. But not so in gedit or a sample app written in gtkmm. 


Requirements:

- add arabic keyboard layout in gnome-settings
- install freely available font "UthmanicHafs1 Ver09.otf"
  -> http://fonts.qurancomplex.gov.sa/download/UthmanicHafs1Ver09Font.zip

How to reproduce:
- select font "KFGQPC Uthmanic Script HAFS" in gedit
- change keyboard layout to arabic
- paste this arabic text in gedit: اللَّه
  -> bug: Text wrongly becomes this: اللهَّ (see screenshot in attachment)
or
- build and run sample app in attachment

How to verify/how it should look like:
- select font "KFGQPC Uthmanic Script HAFS" in LibreOffice
- change keyboard layout to arabic
- paste this arabic text in LibreOffice: اللَّه

I apologize for my bad english and if this bug should be posted else where.

thank you everybody so much.
