解决 UnicodeDecodeError: 'utf-8' codec can't decode byte 0xba in position 5: invalid start byte

在执行以下代码时

@requires_authorization
f = open('红楼梦.txt',encoding='utf-8')
each_line = f.readline()

报错如下：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xba in position 5: invalid start byte

解决方式: encoding=’utf-8’ 改为’GB2312’
