I want to know that when an exception occurs when the program is running in the idea, Chinese descriptions are displayed in the exception in some cases. How is this Chinese display function implemented? (I didn't install the Chinese plug-in package.)

Hi, does this message display in the running process log or in the IDEA editor window? A screenshot might be helpful.

I want to know what Chinese is displayed on the basis of this?

Hi,

All the message in this tool window is generated by java.exe(aka a JVM), and they are not controlled by IDEA anymore, if you run them out of IDEA by command line(eg: using Terminal or Power Shell), it still is there. Usually, the message is created by a java.exe based on your operating system's language settings in the Windows control pane.

For this message:  系统找不到指定的文件, it means there is no such file, or you didn't have the system permission to access it, can you open the folder C:\Users and check is there have such a file? Usually this file should be put under your name folder: C:\Users\you_account_anem\name.pub

Okay, thanks. I'm just consulting the source of this information. The wrong words are just an example of me.
