Type of character properties

val load_property_tbl : character_property_type -> UCharTbl.Bool.t

Load the table for the given character type.

val load_property_tbl_by_name : string -> UCharTbl.Bool.t

Load the table for the given name of the character type. The name can be obtained by removing ` from its name of the polymorphic variant tag.

val load_property_set : character_property_type -> USet.t

Load the set of characters of the given character type.

val load_property_set_by_name : string -> USet.t

Load the set of characters of the given name of the character type. The name can be obtained by removing ` from its name of the polymorphic variant tag.

Canonical Composition

val load_composition_tbl : unit -> (UChar.t * UChar.t) list UCharTbl.t

The return value [(u_1, u'_1); ... (u_n, u'_1)] means for the given character u, u u_i forms the canonical composition u'_i. If u is a Hangul jamo, composition returns .
