6.6.4 Character Sets

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.

• Character Set Predicates/Comparison:

• Iterating Over Character Sets: Enumerate charset elements.

• Creating Character Sets: Making new charsets.

• Querying Character Sets: Test charsets for membership etc.

• Character-Set Algebra: Calculating new charsets.

• Standard Character Sets: Variables containing predefined charsets.
