Can anyone help me in this case?

Just change extension from UFONT to TTF and then edit this file using High-Logic Font Creator.

@anil523, why did you delete all info about this tool?

I want you to share these files if possible !

Please correct the title and add platform (PC, PS3 etc)

and i get .raw

What do you mean by "get .raw"?

This is TTF i found in asset0

You can edit it with High-Logic Font Creator or similar program.

what is .ufnt

I don't know. It looks custom.

how i make it support 100%

You need to find game's fonts and edit them to add characters from your language.
As it's Unity game you can use UnityEx or AssetStudio first.

i want to know it's about TTF and DDS

Not always. Sometimes font can be completely custom.

Maybe you have saved it with wrong RW version or wrong platform, I don't know.
Try different settings or try to get some help on GTA modding community.

What do you mean by "not recognized"?

Both fonts can be opened just fine with Magic.TXD

Is it possible to port the Korean subtitles that exist in the PC version to the XBOX orange box?

Maybe. But that requires some knowledge about Source Engine and Reverse Engineering.
You would also need a modded X360 console to test your changes.
