Yes, we can do this but if we do then we cannot easily drop the MacRoman 
support. But I'm fine with this solution if you prefer it.

Proposal: We add a "utf32Code" field to the sqKeyboardEvent that VMs are 
supposed to fill in if they support extended input services, zero if 
not. Everyone agree on this?

We really should be able to make that distinction by looking at the 
keyDown exclusively. What's so hard about it? It seems that both Win & 
*nix have trivial ways of giving us the information so it seems to me 
that the Mac ought to be able to give us that information too, shouldn't it?

Cheers,
