如何在 VS Code 的终端中打印越南语？

Question

This is my code:

public class Test {
   public static void main(String[] args) {
      System.out.println("Tiếng Việt có dấu");
  }
}

In the VS Code terminal it prints:

Ti?ng Vi?t có d?u

How can I fix it so the VS Code terminal displays the text correctly?

Answer 1

Assuming Windows >= 10:

1. + R , intl.cpl , Enter

2. doing this:

3. Restarting system.

Then (after Restart) we try this in VS Code:

public class Test {
  public static void main(String[] args) throws UnsupportedEncodingException {
    System.out.println("1: Tiếng Việt có dấu");
    try ( PrintWriter consoleOut = new PrintWriter(new OutputStreamWriter(System.out, StandardCharsets.UTF_8))) {
      consoleOut.println("2: Tiếng Việt có dấu");
    }
  }
}

... we get (Run Java, default shell, pwsh.7.2.0 in my case):

PowerShell 7.2.0

PS C:\DEV\projects\test>  & 'C:\Program Files\Java\jdk1.8.0_311\bin\java.exe' '-cp' 'C:\Users\xerx\AppData\Local\Temp\cp_16pw9c0xw9lhctexolmzuqrp.jar' 'Test' 
1: Ti?ng Vi?t c d?u
2: Tiếng Việt có dấu

... but also switching to cmd.exe :

C:\DEV\projects\test>java -cp C:\Users\xerx\AppData\Local\Temp\cp_16pw9c0xw9lhctexolmzuqrp.jar Test 
1: Ti?ng Vi?t c d?u
2: Tiếng Việt có dấu

GitBash??: - "Null Problemo":

picard@enterprise MINGW64 /c/DEV/projects/test (main)
$ java -cp ~/AppData/Local/Temp/cp_16pw9c0xw9lhctexolmzuqrp.jar Test
1: Ti?ng Vi?t c d?u
2: Tiếng Việt có dấu

So the problem is rather not in VS Code or Java, but more "general"/historic/"proprietary" (see the threads linked + What encoding/code page is cmd.exe using? + https://www.google.com/search?q=windows+console+encoding :)

Because in Ubuntu ( wsl ) Shell:

picard@enterprise:/mnt/c/DEV/projects/test$ java -cp ./build/classes/java/main/ Test
1: Tiếng Việt có dấu
2: Tiếng Việt có dấu
