Unicode algorithms for case mapping, word splitting, collation etc.
are generally defined in terms of code points. Character database is
keyed by code points, which is the largest practical text unit with
a finite domain.
Even if on the high level there are some other units, any algorithm
which determines these high level text boundaries is easier to
implement in terms of code points than in terms of even lower-level
UTF-x code units.
