The features described in this section correspond directly to SRFI-14.
The data type charset implements sets of characters (see Characters). Because the internal representation of character sets is not visible to the user, a lot of procedures for handling them are provided.
Character sets can be created, extended, tested for the membership of a characters and be compared to other character sets.
