ascii − the ASCII character set encoded in octal, decimal, and hexadecimal
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.
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 vertical bar has a hole in the middle.
The ASCII standard was published by the United States of America Standards Institute (USASI) in 1968.
