Furthermore, it adds support for the dead keys, which were for some reason present in the keymaps, but not in vnc_keysym.h. This is relevant for VNC viewers that pass dead keys on to the guest system (e.g. tightvnc does) and don't compose the accented letters themselves.
This fixes AltGr with GtkVNC here too. Is there any special reason for
not mapping ISO_Level3_Shift?
