Character not showing properly in Java

Question

I'm trying to get the user name as an input, but whenever I run the code, it doesn't show properly. I tried adding Charset.forName("UTF-8"); but it did not solve the problem.

It shows the same problem in Git Bash and Powershell.

import java.util.Scanner;

public class UserInput {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in, Charset.forName("UTF-8"));

        System.out.print("What is your name? ");
        String name = scanner.nextLine();

        System.out.println("Hello " + name);

    }
}

Console:

What is your name? João
Hello Jo?o

I also tried running "chcp 65001" before running the code and it returns:

What is your name? João
Hello Joo

And then I added this code to try to fix it and I got a different error

import java.io.FileDescriptor;
import java.io.FileOutputStream;
import java.io.PrintStream;
import java.io.UnsupportedEncodingException;
import java.util.Scanner;

public class input {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        try {
            System.setOut(new PrintStream(new FileOutputStream(FileDescriptor.out), true, "UTF-8"));
            System.out.print("What is your name? ");
            String name = scanner.nextLine();

            System.out.println("Hello " + name);
        } catch (UnsupportedEncodingException e) {
            throw new InternalError("VM does not support mandatory encoding UTF-8");
        }

    }
}

Console:

What is your name? João 
Hello Jo´┐¢o

Vscode uses the computer's built-in terminal as an integrated terminal, so this has something to do with your machine language, script encoding, terminal code and many other things. You can try to modify the machine language and other operations to get the correct output, but it will be a little troublesome.

Here's another option to try:

Configure launch,json as follows

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "Current File",
            "request": "launch",
            "mainClass": "${file}",
            "console": "internalConsole"
        }
    ]
}

Then execute the script with Run Without Debugging (Ctrl+F5)
Input in the DEBUG CONSOLE panel
Enter to get the output
