ISO 2047, ECMA-17[3] in Europe, GB\/T 3911-1983 in China, that corresponds to KS X 1010[4] 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.While the ISO\/IEC 646 three-letter abbreviation (such as “ESC”), or caret notation (such as “^[“) are still in use, the graphical symbols of ISO 2047 are considered outdated and rare.[5]  Character table[edit]Code(hex)CommonabbreviationNameSymbol[1][3][6][7][8]2-letterabbreviation00NULNull\u2395U+2395NU01TC1, SOHStart of Heading\u2308U+2308SH02TC2, STXStart of Text\u22a5U+22A5SX03TC3, ETXEnd of Text\u230bU+230BEX04TC4, EOTEnd of Transmission\u2301U+2301[9]ET05TC5, ENQEnquiry\u22a0[10]U+22A0EQ06TC6, ACKAcknowledge\u2713U+2713AK07BELBell\u237eU+237E[9]BL08FE0, BSBackspace\u293a\u2014[11]BS09FE1, HTHorizontal Tabulation\u2aabU+2AABHT0AFE2, LFLine Feed\u2261U+2261LF0BFE3, VTVertical Tabulation\u2a5bU+2A5BVT0CFE4, FFForm Feed\u21a1U+21A1FF0DFE5, CRCarriage Return\u2aaaU+2AAACR0ESOShift Out\u2297U+2297SO0FSIShift In\u2299U+2299SI10TC7, DLEData Link Escape\u229fU+229FDL11DC1, XON, CON[12]Device Control 1\u25f7U+25F7D112DC2, RPT,[12] TAPE[13]Device Control 2\u25f6U+25F6D213DC3, XOF, XOFFDevice Control 3\u25f5U+25F5D314DC4, COF, KMC,[12]TAPE[13]Device Control 4\u25f4U+25F4D415TC8, NAKNegative Acknowledge\u237bU+237B[9]NK16TC9, SYNSynchronization\u238dU+238DSY17TC10, ETBEnd of Transmission Block\u22a3U+22A3EB18CANCancel\u29d6U+29D6CN19EMEnd of Medium\u237fU+237F[9]EM1ASUBSubstitute Character\u2426U+2426[14]SB1BESCEscape\u2296U+2296EC1CIS4, FSFile Separator\u25f0U+25F0FS1DIS3, GSGroup Separator\u25f1U+25F1GS1EIS2, RSRecord Separator\u25f2U+25F2RS1FIS1 USUnit Separator\u25f3U+25F3US20SPSpace\u25b3U+25B3SP7FDELDelete\u25a8\u2014[15]DTReferences[edit]^ a b c “ISO 2047:1975 Information processing \u2013 Graphical representations for the control characters of the 7-bit coded character set”.
