Print to the console in django without UnicodeEncodeErrors

在线下环境的时候，正常运行，然后当线上环境，添加汉字报了如下的bug:

Traceback (most recent call last):  
File "views.py", line 107, in <module>
    print kwargs
UnicodeEncodeError: 'ascii' codec can't encode character u'xa0' in position 20: ordinal not in range(128)

猜测应该是线上环境经过uwsgi的时候出了问题，然后去搜uwsgi django UnicodeEncodeError

得到类似的答案：

http://stackoverflow.com/questions/24887929/locale-on-django-and-uwsgi-unicodeencodeerror

http://chase-seibert.github.io/blog/2014/01/12/python-unicode-console-output.html

看了两篇文章后找到两种解决方案：

1.在uwsgi文件中添加如下配置

env = PYTHONIOENCODING=UTF-8

2.在django的settings.py文件中加入

import sys
import codecs
sys.stdout = codecs.getwriter('utf8')(sys.stdout)
sys.stderr = codecs.getwriter('utf8')(sys.stderr)

以上两种方案经尝试后都解决了那个该bug。

总结：Your termianl can typically handle UTF8 characters just fine. The issue is actually that Python is just getting confused about what encoding the terminal accepts.
