how to change the encoding of the java compilation error message? [closed]

Question

for example,I tried to compile a java file which can not pass the compilation in a cmd line. the java code:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("hello World")
    }
}

cmd line: javac HelloWorld.java

and the compilation error message will be showed in the cmd window.

its encoding is GBK,but the cmd program's encoding is utf-8. How can I change the encoding of the java compilation error message?(I'm using windows 10 and jdk8)

Answer 1

This is a problem with the default codepage on Windows when you use Terminal.

Use the chcp command at the CMD and PowerShell prompt to list the current code page.

On this page: "Code Page Identifiers - Win32 apps | Microsoft Docs" you will find a list of all Windows code pages. Last on the list is utf-8.

In the Windows 10 version (most current in January 2022) we can configure Regional Settings. Chose the Unicode utf-8 Check-box on Regional Settings of Settings/Regional.
