Name
ascii — the ASCII character set encoded in octal,
decimal, and hexadecimal
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.
Tables
For convenience, let us give more compact tables in hex
and decimal.
NOTES
History
An ascii
manual page appeared in Version 7 of 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.
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-microcontroller-based
electronic keyboard and that pairing was found on old
teletypes.
The ASCII standard was published by the United States of
America Standards Institute (USASI) in 1968.
