When launching in integrated/external terminal, the debugger passes commands to vscode, and vscode assembles and sends it to the terminal. But if there's non-ascii char in code/path, the java process will have unexpected behavior, because of bad Unicode support in Windows.

Either VS Code or the extension should do something to cover these cases.

Example

Folder structure:

中文目录
├── Hello.class
└── Hello.java
0 directories, 2 files

Content of file 中文目录/Hello.java:

public class Hello {
  public static void main(String[] args) {
    System.out.println("中文");
  }
}

a) on Mac OSX

Works as expected

$> java -cp 中文目录 Hello
中文

b) on Windows

Non-ASCII char in classpath

Classpath is not correctly recognized by Java, if it contains non-ascii char.

D:\Test>java -cp 中文目录 Hello
Error: Could not find or load main class Hello

Non-ASCII char in stdout

cd into the folder, the classpath is correctly recognized now, but the terminal fails to print non-ascii chars.

D:\Test>cd 中文目录

D:\Test\中文目录>java -cp . Hello
ä??æ??

To display non-ascii char in Windows terminals, you have to modify the code page, see https://ss64.com/nt/chcp.html

Workaround: set code page to 65001 (utf-8)

D:\Test\中文目录>chcp 65001
Active code page: 65001

D:\Test\中文目录>java -cp . Hello
中文
