Ucs_normal.NFKDThe fully-decomposed compatibility normal form.
val quick_check : Ucs_db_aux.qc Ucs_db_aux.mapThe quick-check property corresponding to the form.
val boundary_check : Uchar.t Seq.t -> Ucs_db_aux.qcUse boundary_check s to consume s, and if possible, quickly find whether the sequence conforms to the normalization form.
Returns QC_yes if s is normalized, or QC_no if s is not normalized, and QC_maybe if the predicate can only be determined by the more costly function of comparing the sequence with the output of the transform function (see below).
