There might be multiple obstacles involved (e.g. multiple places that
assumes the chars are all <127), so it'll be important to test things
bit by bit.  E.g. check that with no patch the `input-method-function`
is not called at all when you press F19, then check that with
your patch `input-method-function` *is* called when you press F19.

Once that is done, the rest of the hacking should all be doable at the
Lisp level, but it may involve tracing through the quail code, indeed.
