On the client system, are you having to press Ctrl+Alt to emulate AltGr? Or
do you have a dedicated AltGr key?

The VNC server is supposed to automatically press/release modifier keys as
necessary to type the intended symbol. It sounds like the VNC server is not
doing that quite right, though this is the first I've heard of such issues
with TigerVNC.
