(info "(emacs) Modifying Fontsets")
shows how to
+ Use a certain font for a certain range of characters
+ Prohibit a certain font for all characters
But it doesn't show how to
+ Prohibit a certain font for a certain range of characters
So to prohibit a certain font for just one character, the user must
prohibit it for all characters.
Or he must hardwire some other arbitrary font to be used for that one
character, he can not just say don't use a certain font for that
character.

That's because there is no way. You must instead use another font for
that range of characters.

No.

Yes. Why is that a problem?
I'm not sure I understand what exactly is the bug you would like to be
fixed here? There's no documentation bug, AFAICT, as the
documentation describes the facilities we have.

Is there a null font, that one could specify for that range of characters
and thus prevent use of any other font?

All I know is often a user is trying to communicate through their .emacs that
they don't want to use a certain font for a certain range(s) of
characters, so please give them the power to do that.
Don't force them to have to specify what other font should be used,
and don't force them to ban that whole font completely.
I had to say
(set-fontset-font "fontset-default" #x20AC "AR PL UKai TW MBE"); To see EURO SIGN "€"
because
(add-to-list 'face-ignored-fonts "eten-fixed-medium-r-normal"); Wrecks Chinese
was serious overkill, in

Yes, there is: use nil for the FONT-SPEC argument. But AFAIU, that's
not what was requested, since doing that will always display those
characters as boxes with hex code. What was requested is to have a
feature that will disable the use of just one specific font for a
particular range of characters, thereby forcing Emacs to use some
other font for that range.
