python-2.7 - UnicodeDecodeError：'utf8'编解码器无法解码位置3中的字节0xaf：python 2.7中的无效起始字节

using windows10 python 2.7

我的解密代码


    def decrypt(self, enc):
            enc = b64decode(enc)
            iv = enc[:16]
            cipher = AES.new(self.key, AES.MODE_CBC, iv)
            print cipher,"======"
            dec = cipher.decrypt(enc[16:])
            #print dec,"========",dec
            unp = unpad(dec)
            print unp,"=========","=fdkjfsdklfsdjndjdjk"
            decode = unp.decode('utf8')
            #decode = unp.decode('utf8')
            print decode
            # unpad(cipher.decrypt(enc[16:])).decode('utf8')
            return decode

解密加密响应cipher.decrypt（enc [16：]）行时

给出了我的输出。但实际上它应该是XML格式。

虽然在unp.decode('utf8')行进行解码会出现以下错误

    Traceback (most recent call last):
      File "nic_dycrypt_encrypt.py", line 99, in 
        print('Ciphertext:', AESCipher(key).decrypt(ciphertext))
      File "nic_dycrypt_encrypt.py", line 86, in decrypt
        decode = unp.decode('utf8').strip()
      File "C:\Python27\lib\encodings\utf_8.py", line 16, in decode
        return codecs.utf_8_decode(input, errors, True)
    UnicodeDecodeError: 'utf8' codec can't decode byte 0xaf in position 3: invalid start byte

Please any one help me to know what is that format and why the error is coming and how to resolve
