if stdout is pipelined, python tries to encode its output
to ascii. The following is my solution for python2.6:

from locale import getpreferredencoding
from sys import stdout
try:
    STDOUTENCODING = stdout.encoding
except AttributeError:
    STDOUTENCODING = None
if not STDOUTENCODING:
    STDOUTENCODING = getpreferredencoding()

def kprint(*args, **kwargs):
    """a wrapper around print, always encoding unicode to something sensible"""
    newArgs = [unicode(x).encode(STDOUTENCODING) for x in args]
    # we need * magic: pylint: disable=W0142
    print(*newArgs, sep=kwargs.get('sep', ' '), end=kwargs.get('end', '\n'), file=kwargs.get('file'))
