Tested versions:
- ATS 1.41.1.10s
- ETS2 1.41.1.5s
Since ATS/ETS2 1.36, Windows users can input CJK text using IME. I think the Linux version should provide a way to input CJK text too.
Now the feature is very important because of Convoy: CJK Linux users would be happy if they can communicate in their native languages.
Most input methods support XIM (X Input Method) protocol and ATS/ETS2 Linux version should support XIM for now.
