FWIW, the SQL spec puts the onus of normalization squarely on the
application; the database is allowed to assume that Unicode strings
are already normalized, is allowed to behave in implementation-defined
ways when presented with strings that aren't normalized, and provision
of normalization functions and predicates is just another optional
feature.
