OK.  I did a bit more work on it.  I realized that your example
posted fontsets for a tremedous number of fonts and sizes.  Since I
only work in one font (courier-14), it could be trimmed way down.

This block seems to solve my problem:

      (set-variable 'default-buffer-file-coding-system 'mac-roman-unix)
      (set-default-coding-systems 'mac-roman-unix)
      (set-selection-coding-system 'mac-roman)
      (set-keyboard-coding-system 'mac-roman)
      (prefer-coding-system 'mac-roman-unix)
      (create-fontset-from-fontset-spec

      (setq default-frame-alist
            (append
             '((width . 80)
               (height . 104)
               (font . "fontset-david"))
               default-frame-alist))

The lack of default coding systems (default-buffer-file-coding-system,
set-default-coding-systems, and prefer-coding-system) were what was
ruining the file-insert operation.

Once I did that, all but four characters rendered.  Adding the font
to the fontset for all the other characters solved that problem.

I still think something like this could be, and should be automated.
The fact that every single code-range uses the same font (and appears
to for most of yours as well) tells me that Emacs should assume this
pattern unless explicitly configured otherwise.  Specifying a font
instead of a fontset should tell Emacs to do what you and I already
did - use that one font for all ranges.  This would make the system
backward-compaible and simple to set up for the majority of users.

Ignore that whine.  I took one look at all you wrote and didn't
realize you had simply provided code for 68 fonts, and that you only
need the ones for those fonts you're actually going to be using.

However, I stand by this gripe.  But there's no need for me to dump
my complaint on you.

Thanks for all your help.
