I found a very useful Python package for detecting the encoding of files. It's chardet. 

1. install chardet

pip install chardet

2. an example of how to use it
Python 2

import urllib
rawdata = urllib.urlopen("http://www.baidu.com").read()
import chardet
chardet.detect(rawdata)

Python 3

from urllib.request import urlopen
rawdata = urlopen("http://www.baidu.com").read()
import chardet
print (chardet.detect(rawdata))

3. results
