If you do not know the encoding of Chinese characters, for example, is a piece of text crawling on the Internet (usually do not know)

The Chardet module is used to encode it and convert it to Unicode.

Results:

I love @ embarrassed hundred, you?
[(U ' \u6211\u7231 ', U ' \uff0c\u4f60\u5462 ')]
I love
What about you

Of course, if you want to double-click, py under Windows demo, get the string should be added J.encode ("GBK")

Note: Before processing the Chinese to convert it to Unicode, do not ASCII code directly match, ASCII code how to convert Unicode? Come on.
