Xerox Character Code Standard Version 2.0 1990
Abstract
The purpose of this standard is to permit the storing and transmitting of multilingual textual information in the form of a sequence of numerical codes called character codes. A sequence of such codes forms the body of a string. When two information processing systems share a standard interpretation of character codes and a standard format for strings, they can communicate text without danger of degrading its information content.
This particular standard is used throughout the Xerox systems. It generalizes familiar ISO and ANSI standards for coded character' sets for text communication, and includes numerical codes for rendering entities, that is, non-graphic character codes which may be used in fragments of text.
