Yes, or "Characters detected for which there is no font; `C-h C-F' for
more information", and that would be a new command that'd look for tofu
in the buffer.  (In which case we don't need the variable, but just a
delayed warning, because the new command could do the analysis,
perhaps.)

If we can, that'd be nice.  We do already know (based on the Unicode
data) what scripts the characters are from?  So we could at least list
that, and then expand the help, if we have the stamina, to also include
some fonts.
