The GTK applications do need to display the filenames using X11. How to do
that without assuming that filenames are encoded character sequences?

See above - how to display them without this assumption, if you can't
determine the encoding?

Unfortunately both seem to be necessary for good usability. Or do you have
any other algorithm to display filenames and transforming keyboard input
to filenames in mind?
