Well, gnome_vfs_escape_host_and_path still gives a valid uri so that's
why it works. However, I see now that, just like you say, åäö doesn't
work as metadata in other places (for example, the annotation).

So, my next solution would probably be to write a special xmlGetProp
function that would traverse the xmlAttrPtr tree and unescape any
occuring entities. How does that sound?

Since xmlGetProp in libxml2 returns the entities unescaped in utf8
format this should be no problem.
For URL cases, functions for converting between utf8 filenames and
gnome-vfs uris are probably needed, and for other cases (like the
annotations) we should just be fine since we can display such text with
gtk+2.
