name—a string designator.
char-p—a character or nil
.
Returns the character object whose name is
name (as determined by string-equal
—i.e., lookup is not case sensitive).
If such a character does not exist, nil
is returned.
(name-char 'space) → #\Space (name-char "space") → #\Space (name-char "Space") → #\Space (let ((x (char-name #\a))) (or (not x) (eql (name-char x) #\a))) → true
Should signal an error of type type-error
if name is not a string designator.
