'text' contains Unicode, but you're writing it to a file that's not
opened for Unicode. Either open the output file for Unicode:

     of = codecs.open("umlaut-out.txt", "w", encoding="latin1")

or encode the text before writing:

     text = text.encode("latin1")

(I'm assuming you want the output file to be in Latin1.)
