Hallo,
I tried to use sphinx rst2html to convert rst file to html.

The command was:
C:\python33\Scripts\rst2html.py INSTALL.rst
OS: Windows 7 64bit (Greek)
Python: version 3.3.3

The traceback output is:

Then you actually did not use Sphinx but (pur) Docutils. This means you are
at the right list.

It looks like you found one of the never-ending encoding problems aggravated
by the Python 2-3 divide.

In Python 2, most methods would "do the right thing" regarding unicode<->bytes
conversiond. However, in 3.3.:

The methods on bytes and bytearray objects don’t accept strings as
their arguments, just as the methods on strings don’t accept bytes as
their arguments.

Does the following patch help?
