Another å, ä, ö question

[Martin Schöön]

I am studying some of these tutorials:
https://pythonprogramming.net/matplotlib-intro-tutorial/

I am recreating the code and I use my native Swedish for comments,
labels and titles. Until now I have been doing so using Geany
and executing using F5. This works fine.

But -- now I tested using emacs instead using C-c C-c to execute.
Noting happens so I try to run the program from command line and
find that now Python can't stand my å, ä and ö.

I am puzzled: With Geany there is no problem but outside Geany
I am punished by Python for using Swedish.

Any ideas?
