SRFI-14 defines the data type character set, and also defines a lot of procedures for handling this character type, and a few standard character sets like whitespace, alphabetic characters and others.

All procedures from SRFI-14 (character-set library) are implemented in the module (srfi srfi-14), as well as the standard variables char-set:letter, char-set:digit etc.

• Loading SRFI-14: How to make charsets available.
