An "error message" _when_? Whether a character is displayable or not
isn't known until display time, and error messages for display issues
are generally a very bad idea. For some display errors, the display
code will put messages in the *Messages* buffer (though they aren't
displayed to the user), but even that must be done with careful
consideration; currently they typically indicate that something
seriously screwy is going on (and a non-displayable character, however
annoying, isn't "seriously screwy").
If an "error message" were displayed, what would it say? The only thing
I can think of is "no font could be found to display character FOO", but
that fact is already obvious from the little box. Given no extra
detail, is a message even useful?
Maybe some sort of _once-only_ pop-up buffer note to the user saying
"little boxes indicate characters for which a font could not found; see
info manual section X.Y for details on blah blah"? I suppose that could
help some people, but such a thing, even if once-only, would probably be
pretty annoying to non-complete-noob users, so ...
