That's really a subject for gtk-app-dev (unless you want to contribute a patch, in which case you could write a bug), but:

Well... no, not exactly. Gdkfont has been removed from Gtk+-3 and fonts and layout and such are handled directly by pango; there aren't even any wrappers. It probably works OK there, though I can't say I've tested it. Since 2.24 is a bug-fix end-of-life release series, it's not likely ever to be fixed there. That means that you'll have to wait until Gtk-Ada is ported to Gtk+-3 to have font features fully supported. The good news is that unlike some of the other bindings GtkAda appears to be active.
