This looks like a problem in your environment. "UTF-8" is not a
locale; usually you'll want something else first. For me, it's
"en_AU.utf8" (although I believe UTF-8 works fine in place of utf8).
What language do you primarily speak, and what country are you in? Put
their two-letter codes together, and you'll get something like
"en_US.utf8" (English, USA), or "tr_TR.utf8" (Turkish, Turkey), or
"pt_BR.utf8" (Portuguese, Brazil). Once you know what locale you want
to be using, though, you'll need someone who knows Macs to help you
select that appropriately. Worst case, run this command before
starting Python:

export LC_ALL=en_AU.utf8

That may help.
