The ASCII-Charset

The ASCII charset was developed in 1963 by the ASA and is one of the most basic standards in computer sciences. This standard describes a relation between machine-readable binary code and human readable letters and other characters. The charset contains 128 7bit encoded characters which are uppercase and lowercase latin letters, digits 0 to 9, punctuation characters, a couple of special characters and 33 control characters. Both 8bit character sets and the Unicode character set are based upon ASCII.

The following chart lists the ASCII charset - character names and their corresponding values. The first 32 characters and the last character are control characters which can not be displayed. They are represented by their respective symbols, which depict a slanting abbreviation of their names.

A note on the term charset:
The W3C recommends using the term character encoding instead of the terms charset and character set:
Specifications SHOULD avoid using the terms 'character set' and 'charset' to refer to a character encoding, except when the latter is used to refer to the MIME charset parameter or its IANA-registered values. The term 'character encoding', or in specific cases the terms 'character encoding form' or 'character encoding scheme', are RECOMMENDED.
