• 可怖的unkown encoding.

自从修改了windows终端的编码格式后,就出了各种问题,几乎在终端上执行的软件都运行不了,提示LookupError: unknown encoding: cp65001,如下报错。

C:\Users\本阿信>pip --version

只能怪自己,好好的改什么txt文本编码,现在好了。解铃还须系铃人:暂时在该终端下可以使用pip

C:\Users\本阿信>set PYTHONIOENCODING=UTF-8

C:\Users\本阿信>pip --version
pip 20.0.2 from c:\python27\lib\site-packages\pip (python 2.7)

链接还建议设置全局变量为$env:PYTHONIOENCODING = "UTF-8",但是我搜索了一下,没有找到方法,希望会的朋友邮件我教我。 CHCP 936


UTF-8是unicode编码的一种落地方案:

Unicode符号范围 | UTF-8编码方式 (十六进制) | (二进制) ——————–+——————————————— 0000 0000-0000 007F | 0xxxxxxx 0000 0080-0000 07FF | 110xxxxx 10xxxxxx 0000 0800-0000 FFFF | 1110xxxx 10xxxxxx 10xxxxxx 0001 0000-0010 FFFF | 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx

\x对应的是UTF-8编码的数据,通过转化规则可以转换为Unicode编码,就能得到对应的汉字,转换规则很简单,先将\x去掉,转换为数字,然后进行对应的位移操作即可,需要注意的是先要判断utf-8的位数.
