python报错为：ascii' codec can't encode characters in position

[ycwww]

环境：win10+python 3.4版本，已调为默认uft-8编码。

源代码（放其它人电脑上正常执行，在本机报错）：

#!/usr/python3
import re
import urllib.request
def gethtml(url):
    page=urllib.request.urlopen(url)
    html=page.read()
    return html
def getimg(html):
    reg = r'src="(.*?\.jpg)"'
    img=re.compile(reg)
    html=html.decode('utf-8') #python3
    imglist=re.findall(img,html)
    x = 0
    for imgurl in imglist:
        urllib.request.urlretrieve(imgurl,'%s.jpg'%x)
        x = x+1
html=gethtml("http://news.ifeng.com/a/20161115/50258273_0.shtml")
print(getimg(html))

报错内容：UnicodeEncodeError: 'ascii' codec can't encode characters in position 65-69: ordinal not in range(128)

可能爬到了gb2312的页面，判断再转试试。

html = unicode(html ,'GBK').encode('UTF-8')

换了，还是不行？难道是我的环境有问题？
