Please someone help me.

i want to change the font of command & conquer tiberium wars game. i tried several times but failed. can you help me with this?

i know the font is "russellsquare.ttf", i reinstalled it after adding the letters in my language but it still doesn't support the added letters.

The paths I followed

Exporting:

steamapps\common\Command and Conquer 3 Tiberium Wars\Core\1.0\Misc.big (The program I used to open the file: Final BIG)

The file I exported after opening the file: russell square.ttf

russellsquare.ttf The program I used to edit this file: Fontlab 8

After editing I go to the first file (steamapps\common\Command and Conquer 3 Tiberium Wars\Core\1.0\Misc.big) delete the original russell square.tff file and add the Final BIG edited russell square.tff file.


But it doesn't work. I searched in many forums but I can't find it
Sorry for my bad English
