	Fix bug 326747, Alberto Ruiz:

	* glib/gconvert.c (make_valid_utf8): Change this function to
	replace unknown characters by the Unicode replacement character
	instead of '?', and don't append "(invalid encoding)".
	(g_filename_display_name, g_filename_display_basename): Document
	how to determine if the filename was in an invalid encoding.
