Thanks to Miles Bader I've now got something which can show how the
C-x 8 replacement could in principle work.  Todo:

* Make an input method (or several input methods) which are
  appropriate for this application.  It might be useful to construct
  an input method by computing the union of several other input
  methods (such as latin-1-prefix and latin-1-postfix).

* Put more features in it.  Maybe a prefix arg could ask the user for
  an input method to use for just the next C-x 8 command?

Do you think that this goes in the right direction?

Silence is foo!

;;; Commentary:

;; This file is a demonstration of what a replacement of C-x 8 could

;; especially designed for this.  Thanks a lot to Miles Bader for the
;; meat of the function.
