lispdoc - results for char-length

(flexi-streams:char-length sequence &key (external-format latin1) (start 0)
 (end (length sequence)))
Function: Kind of the inverse of OCTET-LENGTH. Returns the length of the subsequence (of octets) of SEQUENCE from START to END in characters if decoded using the external format EXTERNAL-FORMAT. Note that this function doesn't check for the validity of the data in SEQUENCE. This function is optimized for the case of SEQUENCE being a vector. Don't use lists if you're in a hurry.
  
(char-lessp character &rest more-characters)
Function: Return T if the arguments are in strictly increasing alphabetic order. Case is ignored.

Example:
(defun char-el? (el)
  (let ((char-code (char-code el)))
    (and (>= char-code 0) (<= char-code 127))))
