[Why my 0 A.D. the GUI's character string is error encode]

Why my 0 A.D. the GUI's character string is error encode?

The annex file is main menu picture.

Please help me. Thanks a lot!

----------------------------

My 0 A.D. was built by clang and os is Mac OS 10.13.6.

I followed the link:

https://trac.wildfiregames.com/wiki/Installing_East_Asian_Locales

Now the 0 A.D. game that was installed by this website's dmg file has been Chinese Mod.

But when I put the zh-lang.zip that was same with the dmg game used to the mods/zh/ directory and the 0 A.D. was executed by the cmd:

binaries/system/pyrogenesis -mod=public -mod=zh-lang

It showed that.

And I saved the configuration and launched the game.

But it was still error encode.

 

My test was that:
