-- Abstract     : CHARACTER_SET provides a number of test routines
----------------: which determine if a given character falls into
-- a particular class of characters.  See the visible section for
-- details.  It also provides routines for character and string
-- letter case conversion (to lower case, to upper case) and for
-- naming control characters.
