I suggest adding the following defined constants to the next edition of
The upper bound of character codes in string characters.
(STRING-CHAR-P X) is equivalent to
(AND (<= 0 (CHAR-CODE X))
(< (CHAR-CODE X) STRING-CHAR-CODE-LIMIT))
The upper bound of character codes for characters which may be
readtable indices, i.e. legal first arguments to
SET-SYNTAX-FROM-CHAR, SET-MACRO-CHARACTER, etc.
In many implementations CHAR-CODE-LIMIT is the same as
STRING-CHAR-CODE-LIMIT and READTABLE-CHAR-CODE-LIMIT, but not in all
implementations, for example Symbolics Common Lisp.
