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. _ Marco
