I have some.font files extracted from CC version and they are GB2312. I hope to munge them into the core.lvl of the original game to achieve Chinese localization of the original game.

I started by placing these font files in the following path
\BF2_ModTools\data\_BUILD\Common\MUNGED\PC
I then ran munge.bat, but unfortunately did not successfully Munge it into Core.lvl.

Then I used the SWBF2 PC core.lvl Tool made by @Dark_Phantom to munge. This time, core.lvl changed and the size became 266MB, which was basically equivalent to adding the size of those font files. After I put the munge file into the game, it still cannot display Chinese normally when it runs.
