	Understood and point taken.

   The particular case I'm worried about is letters having more than one
diacritical mark *at the same time*, which is unique to Vietnamese -- as
far as I am informed.  Example is that the lunar new year is called 
"Te^'t",
with both ^ and ' being above the "e".  And the question is just whether
the 3 different ways of composing that character are properly handled
by normalisation.  The same question, though, arises for a variety of 
Vietnamese
letters with diacriticals.
