string->char-set s #!optional base-csprocedure
string->char-set! s base-csprocedure

Return a character set containing the characters in the string S.

If character set BASE-CS is provided, the characters from S are added to it. string->char-set! is allowed, but not required, to side-effect and reuse the storage in BASE-CS; string->char-set produces a fresh character set.
