Oh, I now recollect that Handa-san said at some point that keyboard
input doesn't support UTF-16...

How do other macOS programs read UTF-16 keyboard input?  Maybe you
could use the same way to read the sequences, and then decode them
internally as UTF-16 using coding.c facilities, and feed them into the
Emacs event queue?  Just a thought.
