urllib2 编码问题

Python code

def getWebContent(url):
    response = urllib2.urlopen(url, timeout=20)
    return response.read()

if __name__=="__main__":    
    print(getWebContent("http://www.hao123.com"))

显示的结果中:中文为
<meta name="keywords" content="\xe8\xae\xba\xe5\x9d\x9b" />

<meta name="description" content="\xe8\xae\xba\xe5\x9d\x9b " />


请问如何自动判断页面的编码得到正确的中文?
