char-int

char-int Function

Syntax:

char-int character → integer

Arguments and Values:

character—a character .

integer—a non-negative integer .

Description:

Returns a non-negative integer encoding the character object. The manner in which the integer is computed is implementation-dependent. In contrast to sxhash, the result is not guaranteed to be independent of the particular Lisp image.

If character has no implementation-defined attributes, the results of char-int and char-code are the same.

(char= c1 c2) ≡ (= (char-int c1) (char-int c2))

for characters c1 and c2.

Examples:

(char-int #\A) → 65 ; implementation A 
(char-int #\A) → 577 ; implementation B 
(char-int #\A) → 262145 ; implementation C
