"Single emoji" is ambiguous and basically inaccurate.  It's a single
"grapheme cluster".

It is actually both: the rendering engine asks the font how to display
this sequence, the font provides the response in the form of one or
more font glyphs to use, and the renderer then displays those glyphs.

But that wasn't what I referred to as "terminology mishap".
