Hmm...

No, it should run *before* the buffer is changed, and AFAIK the buffer
*is* changed (by inserting an "a") when you hit the "a".  this "a" will
get removed later (after you hit the "b") before running the
self-insert-command which will (re)do the insertion.

Oh, wait, I see that quail-input-method starts by let-binding
inhibit-modification-hooks, so indeed, before-change-functions won't be run.
Hmm... of course, you can still try

   (add-function :before input-method-function ...)

but since its default value is nil (i.e. incompatible with
add-function), it'll be a bit more tricky (you'll need an :around
advice, and you'll need to check the orig function (in case it's nil)
before calling it).

There's clearly room for improvement here.
