Only if really needed. Adding a text property for this will
complicate the display code which handles this, so I'd rather we
didn't unless we have a _very_ good reason. And I don't see such a
reason, since we are talking about characters that cannot be displayed
by any available font, something that is unlikely to be limited to
just a small region of text.

You mean (set-char-table-range glyphless-char-display ?A "B"), I
presume (the value cannot be a character, only a string).

What for? It's a very significant complication, and I cannot see the
purpose. The string value _must_ use only ASCII characters, precisely
_because_ we want to be sure no recursion will be needed.
