ok. Don't know if it is possible that there is something in the configuration
that stops python from properly detecting the system encoding? Some ten
years ago (while using Python 2.3 :) I wrote myself a function that tries
to detect the system encoding (see below); since it is so old some of the things
that function does may be obsolete now, but I still use it today in
a number of my projects and it still works. If you like you can run this
snippet as a test script and see what it says.
Of course it is also well possible that my guess was wrong and the problem
lies somewhere else.
Best regards
Michael
