Try this:
### get_charset.py ###
import re
import urllib2
def get_charset(url):
resp = urllib2.urlopen(url)
#retrieve charset from header
headers = ''.join(resp.headers.headers)
charset_from_header_list = re.findall('charset=(.*)', headers)
charset_from_header = charset_from_header_list[-1] if
charset_from_header_list else ''
#retrieve charset from html
html = resp.read()
charset_from_html_list =
re.findall('Content-Type.*charset=["\']?(.*)["\']', html)
charset_from_html = charset_from_html_list[-1] if charset_from_html_list
else ''
return charset_from_html if charset_from_html else charset_from_header
