I disagree. These Unicode values are not ordinary, not just like any
other. They are special because each of them represents a ligature of
two ASCII characters, which could just as well be presented as a
series of two characters.
When it is impossible to display the character's ligature, it would be
more useful to display the two ASCII characters than to display an
unhelpful diamond.
We should try to do what is most helpful, not be quick to give up.
