this is not really a problem in python, but the
environment can make it look much harder than
it is.   here are some basic facts, to help you
figure out what's going wrong.

    1. python's string type has no problem with
       non-ascii characters (as long as we're talking
       8-bit character sets, that is).  chr() and ord()
       works as you'd expect -- they convert between
       8-bit characters and unsigned integers.

    2. python has no default encoding -- you have
       to keep track of that yourself (or, easier, make
       sure you convert anything to, say, Latin 1).  if
       you don't know what encoding your data are
       using, figure that out before attempting to do
       something with that data.

    3. in cases where python uses "repr" to prepare
       strings for printing, it converts non-ascii character
       to /ddd representation, instead of sending them
       to the output device as is.

    4. the python interpreter uses "repr" to format
       strings when run in interactive mode, unless
       you use print:

            >>> s = "åäö"
            >>> s
            >>> print s

    5. while Windows usually use ISO Latin 1, MS-DOS

            >>> s = "åäö"
            >>> s
            >>> print s

        (note the different output from repr).

okay, that's enough for now.  let us know if you still cannot
figure out where things go wrong in your program.
