or slightly simpler and good for multi-line strings as well:

 PangoContext *context = gtk_widget_create_pango_context (widget);
 PangoLayout  *layout  = pango_layout_new (context);

 g_object_unref (context);

 pango_layout_set_font_description (layout, font_desc);
 pango_layout_set_text (layout, "Some UTF-8 text", -1);

 gdk_draw_layout (drawable, gc, x, y, layout);

 g_object_unref (layout);


however you probably want to save the context and the layout between
exposures to speed things up a bit.
