I agree that there is a possible confusion between plain text and rich text,
but I wonder whether that confusion is to be sought in my sentence or in...
plane 14 itself.
In fact, such a mark-up would be made by using some *characters* present in
a *plain-text* encoding standard. So, it is rather a case of overlap between
plain text and rich text.
Similarly for other cases, e.g.: BIDI override and embedding, font variants
(for mathematics etc.), width variants for space characters, etc.
