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.
