Encoding on the Internet
Standing for "American Standard Code for Information Interchange", this was the first attempt to provide a character exchange standard. When it was invented in the 1960's, computing limitations limited the set to 2^7 or 128 characters. For more information on how ASCII was developed, you can read this article at CNN.com.
Characters number 1-31 are old control characters designed for teletype machines.
ASCII is structured as followed
NOTE: Sometimes the character number in an encoding scheme is called a code point.
Additional charts can be found at the following Web sites, among others.
NOTE: Some charts may list the decimal number (base-10) as well the hexadecimal (base-16) number and octal (base-8) number. In most cases, you would use the decimal number.
ASCII is notoriously U.S.centric and did not provide for common Western European symbols such as the British £ symbol, accented letters (e.g. ñ, é, ü), or even the ¢ symbol. In addition, it is a 7-bit code restricted to 128 (27) characters, which is too few characters for the many languages which use accents in their spelling.
However, ASCII has been the default standard since its inception, and is an encoding standard available to almost all modern computers all over the world.
