The Multinational Character Set (DMCS or MCS) 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).[1][2] MCS is registered as IBM code page/CCSID 1100 (Multinational Emulation) since 1992.[3][4] Depending on associated sorting Oracle calls it WE8DEC, N8DEC, DK8DEC, S8DEC, or SF8DEC.[5][6]

ISO 8859-1 in 1987.[8]

The code chart of MCS with ECMA-94, ISO 8859-1 and the first 256 code points of Unicode have many more similarities than differences. In addition to unused code points, differences from ISO 8859-1 are:

Since 1982 the urgency of the need for an 8-bit single-byte coded character set was recognized in ECMA as well as in ANSI/X3L2 and numerous working papers were exchanged between the two groups. In February 1984 ECMA TC1 submitted to ISO/TC97/SC2 a proposal for such a coded character set. At its meeting of April 1984 SC decided to submit to TC97 a proposal for a new item of work for this topic. Technical discussions during and after this meeting led TC1 to adopt the coding scheme proposed by X3L2. Part 1 of Draft International Standard DTS 8859 is based on this joint ANSI/ECMA proposal.... Adopted as an ECMA Standard by the General Assembly of Dec. 13–14, 1984.
