Every time you install or upgrade IntelliJ idea, you will not be able to display Chinese in the interface of small problems sweat toss a lot of time. Many of the posts mentioned how to change the project file encoding, but there is no mention of how to solve my problem.
In fact, may be the reason for the programmer's thinking, see the interface of a small square is considered to be a coding problem. In fact, when installing the old version of IntelliJ idea, this is just a font setting problem.
OK, now go straight to the steps and-hopefully next time I won't forget.
1. Click File/settings in the main menu to open the Settings dialog and select Apperance&behavior/appearance
2. Select the font in Chinese to support the font (I chose Jache)
