There are advantages to interpreting and operating on text as though it
were in form NFD.  However, there are still cases where one needs
fractions of a character, such as word boundaries in Sanskrit, though I
think the locations are liable to be specified in a language-specific
form.  U+093E DEVANAGARI VOWEL SIGN AA can have a word boundary in it
in at least 4 ways.
