[Windows Phone 7 Development and Hacking] DJSave:
So me and my friend managed to add Georgian fonts to system, plus added Sylfaen.ttf unicode font , so now we can read websites , mail, in office.

Also we edited system fonts and added Georgian characters to every font, so now we can read Georgian in most apps exept system ones.

thats how we did it:

we placed edited fonts to \Windows\Fonts\ dir

and Sylfaen.ttf to Windows\ dir

Using registry editor we changed

[HKLM\Software\Microsoft\FontPath] (we created this key and it works!)

"FontPath"="\Windows\Fonts"

[HKLM\System\GDI\Fonts]

"sylfaen.ttf"="1"

[HKLM\System\GWE\Menu\PopFnt]

"Nm"="Sylfaen"

[HKLM\System\GWE\Menu\BarFnt]

"Nm"="Sylfaen"

[HKLM\System\GDI\SYSFNT]

"Nm"="Sylfaen"

[HKLM\Software\Microsoft\FontLink\SystemLink]

reboot phone and Georgian fonts work like a charm!

Now we have a problem: we need to make Georgian characters show up in people hub, messages etc. there are still squares instead of letters. can devs around here help us out? that would be awsome

thanks

here is the font deployer file, that deploys fonts to My Documents\My Ringtones dir, from there you must copy fonts to Windows\Fonts\ manualy

these method was tested on HTC HD2 and Samsung Focus 100% working
