Thanks for tips and solutions.
I added at the top of the script

reload(sys)
sys.setdefaultencoding( 'ISO8859-1' )

and that solves the problem. It now shows German and French accented 
chars correctly both when run from Eric4 and from the console.

I found this solution some time ago when I was having problems with 
processing Cyrillic attachments. It feels a bit like a not too elegant 
brute force solution. Should I make an attempt in the style that Tobias 
suggests??
