Multinational Character Set

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 82.139.82.82 (talk) at 20:12, 4 September 2015 (MCS was not an ancestor of Unicode and the reference doesn't say it is.). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

The Multinational Character Set (MCS) is a character encoding created by Digital Equipment Corporation 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.[1][2]

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 ISO 8859-1.[3]

The code chart of MCS with 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:

In the following table, code points that differ from ISO/IEC 8859-1 are colored yellow.
