I use Beautifulsoup and urllib2 to download web pages, but different web page has a different encode method, such as utf-8,gb2312,gbk. I use urllib2 get sohu\'s home page, w

Using BeautifulSoup you can parse the HTML and access the original_encoding attrbute:

import urllib2
from bs4 import BeautifulSoup

html = urllib2.urlopen('http://www.sohu.com').read()
soup = BeautifulSoup(html)

>>> soup.original_encoding
u'gbk'

And this agrees with the encoding declared in the <meta> tag in the HTML's <head>:

<meta http-equiv="content-type" content="text/html; charset=GBK" />

>>> soup.meta['content']
u'text/html; charset=GBK'

Now you can decode the HTML:

decoded_html = html.decode(soup.original_encoding)

but there not much point since the HTML is already available as unicode:

>>> soup.a['title']
u'\u641c\u72d0-\u4e2d\u56fd\u6700\u5927\u7684\u95e8\u6237\u7f51\u7ad9'
>>> print soup.a['title']
搜狐-中国最大的门户网站
>>> soup.a.text
u'\u641c\u72d0'
>>> print soup.a.text
搜狐

It is also possible to attempt to detect it using the chardet module (although it is a bit slow):

>>> import chardet
>>> chardet.detect(html)
{'confidence': 0.99, 'encoding': 'GB2312'}

Another solution.

from simplified_scrapy.request import req
from simplified_scrapy.simplified_doc import SimplifiedDoc
html = req.get('http://www.sohu.com') # This will automatically help you find the correct encoding
doc = SimplifiedDoc(html)
print (doc.title.text)

I know this is an old question, but I spent a while today puzzling over a particularly problematic website so I thought I'd share the solution that worked for me, which I got from here: http://shunchiubc.blogspot.com/2016/08/python-to-scrape-chinese-websites.html

Requests has a feature that will automatically get the actual encoding of the website, meaning you don't have to wrestle with encoding/decoding it (before I found this, I was getting all sorts of errors trying to encode/decode strings/bytes and never getting any output which was readable). This feature is called apparent_encoding. Here's how it worked for me:
```
from bs4 import BeautifulSoup
import requests

url = 'http://url_youre_using_here.html'
readOut = requests.get(url)
readOut.encoding = readOut.apparent_encoding #sets the encoding properly before you hand it off to BeautifulSoup
soup = BeautifulSoup(readOut.text, "lxml")
```
