I have built a Django management command that prints out some stuff on stdout (using print). All works fine, but...
我已经构建了一个Django管理命令，可以在stdout上打印出一些内容（使用print）。一切正常，但......
When I try to redirect the output to a file, using
当我尝试将输出重定向到文件时，使用
./manage.py my_command > a_file.txt
I get:
我明白了：
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2013' in position 14: ordinal not in range(128)
No traceback, just that.
没有追溯，就是这样。
I tried ./manage.py my_command | less just for the fun of it, and it showed some output, presumably lines before first non-ASCII char was encountered. Output has some UTF-8 chars, no way around that.
我试过./manage.py my_command |不仅仅是为了它的乐趣，它显示了一些输出，可能是在遇到第一个非ASCII字符之前的行。输出有一些UTF-8字符，没办法。

What's happening here, and how can I dump the info to a file?
这里发生了什么，以及如何将信息转储到文件中？

You can change the standard output of the script with UTF-8 encoded output :
您可以使用UTF-8编码输出更改脚本的标准输出：
import sys
import codecs
sys.stdout = codecs.getwriter('utf8')(sys.stdout)
Or you can encode your strings before printing them:
或者您可以在打印之前对字符串进行编码：
print string_containing_unicode.encode('utf-8')
