My maven repository contains Chinese path "D:\备份\LocalRepository\apache-maven"

*.argfile is auto generated by Java debugger, you cannot change its encoding through settings.json. From my experiment, it seems the encoding of *.argfile is not important. On Windows, I add Chinese string to the classpath, then run the app with *.argfile, it works well for me.

Based on my experience, if you want to use Chinese file path or input/output Chinese characters in Java, the best way is to change your current system locale to Chinese.

Update:
The program will report "java.lang.NoClassDefFoundError" if it accesses the class from the Chinese classpath.

Current workaround is to disable *.argfile. Go to .vscode/launch.json, change the launch setting to "shortenCommandLine": "none".

If launch.json doesn't exist, use the following approach to generate one first.
