Setting the correct encoding when piping stdout in Python

When piping the output of a Python program, the Python interpreter gets confused about encoding and sets it to None. This means a program like this:

# -*- coding: utf-8 -*-
print u"åäö"

will work fine when run normally, but fail with:

UnicodeEncodeError: ‘ascii’ codec can’t encode character u’\xa0′ in position 0: ordinal not in range(128)

when used in a pipe sequence.

What is the best way to make this work when piping? Can I just tell it to use whatever encoding the shell/filesystem/whatever is using?

The suggestions I have seen thus far is to modify your site.py directly, or hardcoding the defaultencoding using this hack:

# -*- coding: utf-8 -*-
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
print u"åäö"

Is there a better way to make piping work?
