Code page 1023 (CCSID 1023), [1] also known as CP1023 or E7DEC, [2] is an IBM code page number assigned to the Spanish variant of DEC's National Replacement Character Set (NRCS). [3] [4] [5] The 7-bit character set was introduced for DEC's computer terminal systems, starting with the VT200 series in 1983, but is also used by IBM for their DEC emulation. Similar but not identical to the series of ISO 646 character sets, the character set is a close derivation from ASCII with only eight code points differing.

ISO/IEC 8859-15:1999, Information technology — 8-bit single-byte coded graphic character sets — Part 15: Latin alphabet No. 9, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1999. It is informally referred to as Latin-9. It is similar to ISO 8859-1, and thus also intended for “Western European” languages, but replaces some less common symbols with the euro sign and some letters that were deemed necessary: This encoding is by far most used, close to half the use, by German, though this is the least used encoding for German.

The Multinational Character Set is a character encoding created in 1983 by Digital Equipment Corporation (DEC) for use in the popular VT220 terminal. It was an 8-bit extension of ASCII that added accented characters, currency symbols, and other character glyphs missing from 7-bit ASCII. It is only one of the code pages implemented for the VT220 National Replacement Character Set (NRCS). MCS is registered as IBM code page/CCSID 1100 since 1992. Depending on associated sorting Oracle calls it WE8DEC, N8DEC, DK8DEC, S8DEC, or SF8DEC.

The National Replacement Character Set (NRCS) was a feature supported by later models of Digital's (DEC) computer terminal systems, starting with the VT200 series in 1983. NRCS allowed individual characters from one character set to be replaced by one from another set, allowing the construction of different character sets on the fly. It was used to customize the character set to different local languages, without having to change the terminal's ROM for different countries, or alternately, include many different sets in a larger ROM. Many 3rd party terminals and terminal emulators supporting VT200 codes also supported NRCS.

Code page 1010, also known as CP1010, is the French version of ISO/IEC 646.

The German standard DIN 66003, also known as Code page 1011 by IBM, Code page 20106 by Microsoft and D7DEC by Oracle, is a modification of 7-bit ASCII with adaptations for the German language, replacing certain symbol characters with umlauts and the eszett. It is the German national version of ISO/IEC 646, and also a localised option in DEC's National Replacement Character Set (NRCS) for their VT220 terminals.

Code page 1012, also known as CP1012 or I7DEC, is IBM's code page for the Italian version of ISO 646, also known as ISO 646-IT IR 15. The character set was originally specified in UNI 0204-70. It is also part of DEC's National Replacement Character Set (NRCS) for their VT220 terminals.

The 7-bit character set was introduced for DEC's computer terminal systems, starting with the VT200 series in 1983, but is also used by IBM for their DEC emulation. It is called DUTCH by Kermit.

Code page 1287, also known as CP1287, DEC Greek (8-bit) and EL8DEC, is one of the code pages implemented for the VT220 terminals. It supports the Greek language.

<span class="mw-page-title-main">DEC Special Graphics</span>

DEC Special Graphics is a 7-bit character set developed by Digital Equipment Corporation. This was used very often to draw boxes on the VT100 video terminal and the many emulators, and used by bulletin board software. The designation escape sequence ESC ( 0 switched the codes for lower-case ASCII letters to draw this set, and the sequence ESC ( B switched back. IBM calls it Code page 1090.
