ISO 2047
ISO 2047 (Information processing – Graphical representations for the control characters of the 7-bit coded character set) is a withdrawn proposal for graphical representation of the control characters for debugging purposes, such as may be found in the character generator of a computer terminal; it also establishes a two-letter abbreviation of each control character. In addition, RFC 1345 "Character Mnemonics & Character Sets" is cited as the ISO 2047 two-letter abbreviation of the control character. ISO 2047, ECMA-17[1] in Europe, GB/T 3911-1983 in China, that corresponds to KS X 1010[2] in Korea (formerly KS C 5713) has been established as a standard. It was enacted "graphical representation of information exchange capabilities for character" JIS X 0209:1976 (former JIS C 6227) in Japan, and was abolished on January 20, 2010.
The ISO/IEC 646 three-letter abbreviation (such as "ESC"), or caret notation (such as "^[") are used much more often than this standard.[citation needed]
