记一次pytest运行报错-UnicodeDecodeError: 'gbk' codec can't decode byte 0xb0 in position 26: illegal multiby

最近学习pytest时，配置pytest.ini后，运行pytest报错，错误如下：

UnicodeDecodeError: 'gbk' codec can't decode byte 0xb0 in position 26: illegal multibyte sequence

解决办法：
更改pytest.ini 文件编码方式为GBK，再次运行不在报错。

原因：
目前未知，不知道具体为什么要这样更改，先记录以便后续跟进。
