关于用python的requests模块返回编码乱码问题

[liwan123]

import requests
import lxml
from lxml import etree
url = 'http://www.chinacoalchem.com/news.asp?id=60719'
loginurl = "http://www.chinacoalchem.com/loginchk.asp?action=pw"
postdata = {
'userid':'liwan123',
'password':'lishichao1',
'UserLogin':'True',
'Submit.x':'25',
'Submit.y':'14'
}
res1 = requests.post(loginurl, data=postdata)
res2 = requests.get(url, cookies=res1.cookies)
res2.encoding = 'gb2312'
res2 = res2.text

xmlcontent = etree.HTML(res2)
links = xmlcontent.xpath('//@href')
for link in links:
print link
代码如上，运行结果如下：
Traceback (most recent call last):
File "D:/python-work/demo.py", line 23, in <module>
print link
UnicodeEncodeError: 'gbk' codec can't encode character u'\xb2' in position 34: illegal multibyte sequence

不知道该怎么该好，怎么设置都有问题，

好像涉及到中英文字符混合的问题，程序出错的那个地方正好是一个含有中文的网址： u'http://www.blogcn.com/zlzj/tougao.\xb2\xa9\xce\xc4\xd4\xad\xb4\xb4.html' 中文部分是“博文原创”

前面都不要转 在最后面转 print link的时候 print link.decode('gbk')
