The Z-machine and Non-BMP Unicode

[Dannii]

Is UTF-16 or UTF-32 a viable option for the Å-machine?

But I’m not really in the Z-Machine interpreter game anymore (ZVM isn’t even used by Parchment now.) If the community wants to try this, go ahead. Maybe there’ll be enough momentum for it to take off this time.

I don’t think this can be gated by standard 1.2. As you note, we’ve had 1.2 proposals kicking around for a while, so there’s a concept of what 1.2 “should” look like. That would have to be resurrected so there’s complete agreement on what a claim of 1.2 actually means, and I’m not sure that’s feasible.

I don’t think there are any interpreters in current use that implement any version of 1.2. The only thing my proposal contained was a @gestalt opcode, so a minimum implementation is easy to make.

David Fillmore’s other proposal isn’t even online anymore. Though I’d forgotten there was a UTF-16 discussion there too.

Z-Machine 1.2 is still an option. But I won’t be championing it this time.
