Multinational Character Set
Template:Short description Template:Infobox character encoding 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).<ref name="vt220_pr"/><ref name="TinyTERM"/> MCS is registered as IBM code page/CCSID 1100 (Multinational Emulation) since 1992.<ref name="CP1100"/><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Depending on associated sorting Oracle calls it WE8DEC, N8DEC, DK8DEC, S8DEC, or SF8DEC.<ref name="Oracle_2002_DEC"/><ref name="Daylight_DEC"/>
Such "extended ASCII" sets were common (the National Replacement Character Set provided sets for more than a dozen European languages), but MCS has the distinction of being the ancestor of ECMA-94 in 1985<ref name="ECMA_1985_ECMA94_R1"/> and ISO 8859-1 in 1987.<ref name="Czyborra_1998"/>
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:
MCS code point | Unicode mapping | Character |
---|---|---|
0xA8 | U+00A4 | ¤ |
0xD7 | U+0152 | Œ |
0xDD | U+0178 | Ÿ |
0xF7 | U+0153 | œ |
0xFD | U+00FF | ÿ |
