Crash on invalid unicode character

[adamreid]

on /r/rust today there's a link entitled "Let's avoid having both foo() and foo_opt()" and it seems the apostrophe in "Let's" is raising a UnicodeEncodeError. Here's a repr of the string in question:
u'\x1b[92m 5 -> \x1b[93m23 \x1b[94mLet\u2019s avoid having both foo() and foo_opt()'

And the traceback.

Traceback (most recent call last):

setting environment variable PYTHONIOENCODING to utf8 should fix the isssue
