   This error is a manual check from java debugger, we can fix it, but i'm afraid you may meet other problems at running class with unicode name. So please ignore this error first, and click "Fix" button to go on and see whether it works.

   And when i tried to use javac in CMD to compile a class with unicode in the file name, actually it won't succeed.

   It is working out of the box with maven compile. For javac via console you have to add "javac -encoding utf8 SüperClass.java".
   Everything else regarding unicode is luckily working/running without a problem (now in 2020). I have an already deployed & running project (created with eclipse/maven) which i was trying to move to vscode now.

   So please ignore this error first, and click "Fix" button to select the target class to go on and see whether it works.

   Ping again.

   ConfigError: 'de.süper.SüperMain' is not a valid class name. is easy to fix, but i need know whether there are other problems.

   If i press 'Fix' and select the class to run an error shows up:
   Fehler: Hauptklasse SüperMain konnte nicht gefunden oder geladen werden Ursache: java.lang.ClassNotFoundException: SüperMain

   Actually i get the same error when trying it in CMD and other IDEs like Eclipse/Intellij IDEA.

   Below are the steps i tried in CMD. javac works, but java execution will throw ClassNotFoundException.
   javac -encoding utf8 xyz
java -Dfile.encoding=UTF-8 -cp . xyz

   Here is a working example:

   Windows 10/openjdk 11.0.3 2019-04-16/Git Bash

   mkdir süper-app
   cd süper-app/
   mkdir de
   mkdir de/süper
   echo -e "package de.süper;\n\npublic class SüperClass {\n\tpublic static void main(String[] args) {\n\t\tjava.lang.System.out.println(\"Hello Unicode\");\n\t}\n}\n" > de/süper/SüperClass.java
   javac -encoding utf8 de/süper/SüperClass.java
   java de/süper/SüperClass
   

   Will print

   Hello Unicode
