如何使用Java从属性中获取韩语字符的值

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public class Main {
    public static void main(String[] args) {
        Properties properties = new Properties();
        try (InputStream input = new FileInputStream("config.properties")) {
            properties.load(input);
            String koreanValue = properties.getProperty("korean");
            System.out.println("韩语字符的值：" + koreanValue);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

System.setProperty("file.encoding", "UTF-8");
