That character is outside of cp437 - the default terminal encoding on
many Windows systems. You will either need to change the code page to
something that supports the character (if you're going to change it, you
might as well change it to cp65001 since you are using 3.3), catch the
error and replace the character with something that is in the current
codepage (don't assume cp437; it is not the default everywhere), or use
a different character completely. If it works on Python 2, it's probably
changing the character automatically to a replacement character or you
were using IDLE, which is graphical and is not subject to the weird
encoding system of terminals.
