The problem with this is that the standard sorting specifications are
done on the whole characters, not the "decomposed" composite
sequences. Also for that reason it would be advantegous to code
the information in the 10646 characters so you have support for
sorting.  Building on the 10646 standard allows you to draw on
all other ISO standardized work building on the standard, and thus
to have an aligned set of standard conforming specifications.
