Message:

Make formatted_text a bit smarter regarding to encodings. It now
returns a unicode string instead of raw strings. I stumbled
over some broken PDF generations when names of students contained
umlauts. Hope, this will fix this without breaking other things. At
least reportlab is able to cope with unicode strings.
