I just upgraded to Ubuntu 11.10 from 11.04 on a Shuttle computer and gnome-terminal is having the same problem when the Maori layout is installed. I currently have the English (US), Spanish, and Maori layouts installed, and key combinations with AltGr on both the Spanish and Maori layouts produce the same 'question mark in diamond' character on the screen.

Linux shuttle 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 17:34:21 UTC 2012 i686 athlon i386 GNU/Linux
model name : AMD Athlon(tm) XP 2500+
cpu MHz : 1825.704
So the bug occurs with gnome-terminal as well as the xfce terminal program. I do not have my Hawaiian layout installed, only what comes with 11.10. This computer did not have that installed in 11.04 - it had been idle for a number of months before this upgrade.
I plan to upgrade to the 12.04 beta2 (plus current updates) overnight.
