This is partly a locale issue; your terminal (command prompt) is using a
locale yet unsupported by python. You can use 'chcp' to switch to
different terminal code page (e.g. use chcp 1250). You won't be able to
'print' arabic characters, but at least python should run.

You're using Python 3.1, the cp720.py file you copied is for Python 2.7
(trunk); there are some backward incompatible between python 2 and
python 3 (specifically in your case, unicode string is now default in
python 3, so unicode literal is no longer supported). Try using the
cp720.py from py3k branch:
