pandas的read_csv读入csv文件报错'utf-8' codec can't decode byte 0xb2 in position 0: invalid start byte

读取CSV文件时，设置'utf-8'，'gb2312' 两种编码都报错，最终改为 'gb18030'读取成功。

read_csv(filename, encoding ='utf-8')

报错：'utf-8' codec can't decode byte 0xb2 in position 0: invalid start byte

read_csv(filename, encoding ='gb2312')

报错：'gb2312' codec can't decode byte 0xad in position 8: illegal multibyte sequence

正确代码：read_csv(filename, encoding = 'gb18030')
