Gtk+ uses UTF-8 everywhere for everything[*] so I am almost sure that
you do not pass UTF-8 even if you think so.  Most likely your strings
were double-encoded to UTF-8.

[*] The only exception are functions working with file names that might
to be in on-disk encoding, or something else, see

http://library.gnome.org/devel/glib/stable/glib-Character-Set-Conversion.html
http://library.gnome.org/devel/gtk/stable/GtkFileChooser.html#gtkfilechooser-encodings
etc.
