在VSCode中，我无法在java中输入utf-8字符串(使用扫描仪！)

// -*- coding: utf-8 -*-

String str = "\u4F60";

import java.util.Scanner;
import java.io.UnsupportedEncodingException;

public class Main {
    public static void main(String[] args) {
        try {
            Scanner scanner = new Scanner(System.in, "UTF-8");
            scanner.useDelimiter(System.getProperty("line.separator"));
            
            System.out.println("请输入字符串：");
            String input = scanner.next();
            
            System.out.println("输入的字符串是：" + input);
            
            scanner.close();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }
}
