Chart example? What chart example? I suppose you mean the
character map application example in which "zilch" is that
which is gained.

Right. It doesn't mean that. It also doesn't mean that a
user should be barred from selecting a font which does exactly
that, though, if that's what the user wants.
As mentioned before, it is *Microsoft* which recommends fonts
include a display glyph for isolated ZWJ's, not me.
And, this recommendation comes from Microsoft's *typography*
specifications, which is where it belongs!

Again, if the user selects a font which uses such boxes, then the
user is NOT expecting invisibility. And, again, populating charts
*is* one of many normal uses of a font.

I know what I want to see.
Now, if I understand your paragraph above correctly, if a user
enters (base) + (VS2) and the system displays (base) + (VS3),
that's perfectly correct? *That* doesn't sound right, either.
