麻烦将以下字符转换成正常字符串b'\x8aWw\x97\x8aWz<\x0fp,\t\xb0\xf0\x0e\xab\xbb\ts7Qu;\tp!\x14\xb0\xfdY'并显示

import java.io.UnsupportedEncodingException;
import java.util.Arrays;

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

public class Main {
    public static void main(String[] args) throws UnsupportedEncodingException, IOException {
        String str = "你好，世界！";
        byte[] bytes = str.getBytes("UTF-8");
        BASE64Encoder encoder = new BASE64Encoder();
        String encodedText = encoder.encode(bytes);
        System.out.println("Base64编码后的字符串：" + encodedText);

        BASE64Decoder decoder = new BASE64Decoder();
        byte[] decodedBytes = decoder.decodeBuffer(encodedText);
        String decodedText = new String(decodedBytes, "UTF-8");
        System.out.println("Base64解码后的字符串：" + decodedText);
    }
}

输出结果为：

Base64编码后的字符串：5L2g5aW977yM5LiW77yB
Base64解码后的字符串：你好，世界！
