That would depend on whether python thinks sys.stdout can
handle UTF8.  For example, on my MacOS X box:

$ python2.6 -c 'print u"abc\u2013def"'
abc–def
$ python2.6 -c 'print u"abc\u2013def"' | cat
Traceback (most recent call last):
  File "<string>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2013' in
position 3: ordinal not in range(128)

This is because python knows that my terminal is capable
of handling UTF8, but it has no idea whether the program at
the other end of a pipe had that ability, so it'll fall
back to ASCII only if sys.stdout goes to a pipe.

Apparently the OP has a terminal that doesn't handle UTF8,
or one that Python doesn't know about.


Hope this helps,
