i need help with custom font for localization

[Neo_Atlantis]

hello
me and my friends are making the korean localization, but there is a problem : Some characters in Korean are not supported.
work fine on the launcher, but Some characters are not implemented in game. (Displayed as special characters or figures.)

I want to create a new font file and modify the dif file, but I don't know how to do it.

I want to implement all the characters used in real life so that they can be used in in-game tips, messages, and chat.
Can you figure out the pattern format of a dif file or tell me how to convert .fnt to .dif? (Where can I get the fontscript? download link is dosn't work/not bm)
