Thanks for this pointer, which I saved for later study.

New concepts for me in this `compose-region'!  Handa-san strikes again! :-)

I confess I do not understand much of it.  Ctrl-S being turned into a
rectangle is mysterious.  Is it the standard way for Emacs to tell about
a non-printable character?  The documentation of font-lock-add-keywords
does not hint me at what may be those S-exprs which are not faces.

Moreover, the effect is a bit tiny or shy, at least compared to what I
expected.  The suggestions of John Miller yield tiny characters as well.
Presumably, I could try to see if I can force higher font sizes, but
that would be diving deeper into trickery, and away from other problems.
Despite the undoubtedly ingenious suggestion, I guess I'll merely stick
with what Org mode already offers, as it's the best I got so far! :-)

In any case, I'm grateful for your interest, and for sharing ideas.
