You should set it to raw-text, do your mouse code preprocessing, and
afterwards decode the remainder using the intended coding system.
Like this?
(defun xterm-mouse-pos-read ()
   (let ((old-coding (keyboard-coding-system)))
     (set-keyboard-coding-system 'raw-text)
         (cons (xterm-mouse-event-read) (xterm-mouse-event-read))
       (set-keyboard-coding-system old-coding))))
You can't go setting the keyboard reading system back and forth.  It
operates into a buffer even before calling read-char.  You have to put
it to raw and stick with it.
Makes sense. That's why I was hoping there was a way intercept input before coding systems get their claws on it. Otherwise xt-mouse finds itself worrying about what coding system the user has requested, whether it changed recently, etc.

If coding systems stacked (and if user-defined ones worked properly) it might be easier, but AFAIK neither is true.

Is there really no other way to do this?
