import java.nio.charset.StandardCharsets;

public class Test {
    @SneakyThrows
    public static void main(String[] args) {
        String s="彐";
        System.out.println("彐");
        byte[] gbks = s.getBytes("gbk");
        System.out.println(((int) gbks[0]& 0x0FF));
        System.out.println(((int) gbks[1]& 0x0FF));
