It occurs to me that when a future version of Unicode is released with
new combining marks, text that mixes old and new marks on the same
base character, or that generates incorrectly ordered new marks,
will produce inconsistent results when passed through normalization.
Consider the sequence LATIN SMALL LETTER A, COMBINING GRACKLE (a
post-3.0 character of class 232), COMBINING ACUTE ACCENT.
A 3.0 implementation of normalization will not recognize the
COMBINING GRACKLE as a mark, and will not swap it with the
acute mark. A post-3.0 implementation with updated tables
will do so.
What is the current thinking on this?
