ASCII(7)		   Linux Programmer's Manual		      ASCII(7)

NAME
       ascii - the ASCII character set encoded in octal, decimal, and hexadec-
       imal

DESCRIPTION
       ASCII is	the American Standard Code for Information Interchange.	 It is
       a  7-bit	 code. Many 8-bit codes	(such as ISO 8859-1, the Linux default
       character set) contain ASCII as their lower  half.   The	 international
       counterpart of ASCII is known as	ISO 646.

       The following table contains the	128 ASCII characters.

       C program '\X' escapes are noted.

HISTORY
       An ascii	manual page appeared in	Version	7 AT&T UNIX.

       On  older  terminals, the underscore code is displayed as a left	arrow,
       called backarrow, the caret is displayed	as an up-arrow and the	verti-
       cal bar has a hole in the middle.

       Uppercase and lowercase characters differ by just one bit and the ASCII
       character 2 differs from	the double quote by just one bit,  too.	  That
       made it much easier to encode characters	mechanically or	with a non-mi-
       crocontroller-based electronic keyboard and that	pairing	was  found  on
       old teletypes.

       The  ASCII standard was published by the	United States of America Stan-
       dards Institute (USASI) in 1968.
