I try to translate English to Chinese by manually edit the message.yml, but after a few reboots, the file got extremely big:

And when I open it (hardly can...):

I can't scroll pass Line 34. Seems the charset is wrong.

Translate then save in UTF-8:

After reboot the server:

start your server with utf-8.

I'll dig up the command line argument.

For reference, are you using Windows or Linux for your server?

Add -Dfile.encoding=UTF-8 to your start script.

I'm using Windows Server w/ Simp. Chinese locale.

-Dfile.encoding=UTF-8 works, thank you!
