You may be right, Philippe. This would all be rather complex to
implement in a word processor when a user selects different diacritics
and gives them all different colours. But it is implementable.
Of course there is an even simpler way to provide the glue I was talking
about. W3C simply needs to relax the rule forbidding combining marks at
the start of a string (and interpret the one precomposed character with
">" as base as if it were decomposed, as I suggested before), and,
remembering that use of NFC is a strong recommendation rather than a
requirement, not insist on NFC in such cases. Then nothing needs to be
added to Unicode.
