如何解决python中UnicodeDecodeError: 'utf-8' codec can't decode byte 0xxx in position xxx: invalid continuation byte问题

出现类似问题，是这个字节超出了utf-8的表示范围，出现了解码错误

解决方案：设置encoding = 'ISO-8859-1'

串口：

data_count = data_ser.inWaiting()
# print(data_count)
if data_count != 0:
    recv = data_ser.read(data_ser.in_waiting)
    print(recv)
    print(recv.decode("ISO-8859-1"))

比如：

with open('./xxx.txt',encoding='ISO-8859-1') as f:
    print(f.read())
