Hi Moritz,
I think you're right. I didn't understand, although I'm already following much of the advice in the your article.
Interestingly, I was already using utf-8 encoding in all my files except this one. I so rarely have to do anything to the filesave default, that I forgot they were there. In fact both the fixes suggested here worked (correcting the file encoding and inserting  in front of the degrees sign).
Thanks for everything
Regards
Steve
