Python3.6（windows系统）解决编码问题

1，py文件代码：

import urllib.request
url = "http://www.douban.com/"
webPage = urllib.request.urlopen(url)
data = webPage.read()
data = data.decode('UTF-8')
print(data)
print(type(webPage))
print(webPage.geturl())
print(webPage.info())
print(webPage.getcode())

2，执行出现字符编码异常：

python, 'gbk' codec can't encode character '\u2122' in position 42161: illegal multibyte sequence

3，解决方案：

#增加字符编码转换
import sys, io
# Change default encoding to utf8  
sys.stdout = io.TextIOWrapper(sys.stdout.buffer,encoding='utf8')
