Thanks for all the hints. After reading Michael's first mail I  
unlocked the preference and asked all my users (10 in number) to  
change to UTF-8. Reading Arjen's mail I'm asking myself if I should  
better delete that preference as Arjen suggests. There is no need for  
us to change from UTF-8 to another charset. What do you propose?
