When I input the Chinese character,it shows normally at first.But after closing the tab and open it again,it will be garbled.

Closing the tab,open it again,it's garbled.

I debug the mod in the IDEA and it doesn't show this problem.

This is an issue with minecraft not using utf8 by default, intellij by default forces utf8 which is why it doesnt happen, theres not much i can really do as its a java argument which i cannot modify

I force the minecraft to launch by using utf8 and it works well now.Maybe the mods need to judge the users's format before saving the json.
