We've already pointed you to a solution which you might want
to use. Why don't you just try it ?
BTW, if you want to read up on all the reasons why Unicode
was done the way it was, have a look at:
and read up in the python-dev archives:
and the next months after the initial checkin.

None of them is perfect, but that's seems to be an inherent
problem with Unicode no matter how you try to approach it -
even more so, if you are trying to add it to a language that
has used ordinary C strings for text from day 1.
