This step is problematical ... it's easy enough to do in GLib-2.0, but
since the NFC transformation is not reversible, if a filename is not
in NFC already, this transformation will loose information that we
need to uniquely, or at least, efficiently, identify the file.

I don't think we should do this in GLib. You couldn't call open() on
the result of the filename => URI => filename transformation and
expect it to work.
