The characters are ordered according to a superset of the ASCII character set.

Platform Dependent: Only in CLISP built with compile-time flag UNICODE: More precisely, CLISP uses the 21-bit UNICODE 3.2 character set (ISO 10646, also known as UCS-4).

Platform Dependent: UNIX (except NeXTstep), Win32 platforms only, and only in CLISP built without compile-time flag UNICODE.

More precisely, CLISP uses the ISO Latin-1 (ISO 8859-1) character set:

	#x0	#x1	#x2	#x3	#x4	#x5	#x6	#x7	#x8	#x9	#xA	#xB	#xC	#xD	#xE	#xF
#x00	**	**	**	**	**	**	**	**	**	**	**	**	**	**	**	**
#x10	**	**	**	**	**	**	**	**	**	**	**	**	**	**	**	**
#x20		!	"	#	$	%	&	'	(	)	*	+	,	-	.	/
#x30	0	1	2	3	4	5	6	7	8	9	:	;	<	=	>	?
#x40	@	A	B	C	D	E	F	G	H	I	J	K	L	M	N	O
#x50	P	Q	R	S	T	U	V	W	X	Y	Z	[	\	]	^	_
#x60	`	a	b	c	d	e	f	g	h	i	j	k	l	m	n	o

Here ** are control characters, not graphic characters. (The characters left blank here cannot be represented in this character set).

Platform Dependent: NeXTstep platforms only, and only in CLISP built without compile-time flag UNICODE.

More precisely, CLISP uses the NeXTstep character set:

	#x0	#x1	#x2	#x3	#x4	#x5	#x6	#x7	#x8	#x9	#xA	#xB	#xC	#xD	#xE	#xF
