CUMUL模型复现与pcap文件读取问题

Question

在解码pcap文件并读取时，这部分出现了错误，如果不加utf-8会报gbk错误，加了以后
File "E:\PYTHON\lib\codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 0: invalid continuation byte
请求帮助我解决这个问题

def decodeTxt(filePath):
    times = []
    length = []
    packetNum = 0
    with open(filePath, "r",encoding="utf-8") as file:
        for dada in file:
            dada = dada.split(" ")
            times.append(float(dada[0]))
            length.append(int(dada[1]))
            packetNum += 1
    return times, length
