Thanks very much.  It seems to work.

I suggest adding comments at the start of the output explaining the
way to use the output.  And moving point to the start, so the user
sees the comments.  For example:

;; Evaluate the Lisp code below to make Emacs show the standard
;; replacement character as a substitute for each undisplayable character.
;; One way to do that is with C-x h M-x eval-region RET.
;; Normally you would put this code in your Emacs initialization file,
;; perhaps conditionally based on the type of terminal.
