Looks like a great engine! Pity it doesn't support non-Basic Latin names for rooms and verbs...
It's just the internal names that have to be basic letters, numbers and underscores, if that's what you mean. You can set the display names to anything you like:
game Dïåcritics
id diacritics
room hagatna You're in downtown Hagåtña.
thing cajon Cajón
name cajón
loc hagatna
verbs play
verb play cajon
display plåy
prompt plåy {$this}
say It sounds better than Motörhead!
