Euromath system: alphabets and fonts

Abstract

We describe some of the principles behind the design of the Euromath system, concentrating on some aspects that are needed to explain how the system deals with alphabets and fonts and are not immediately apparent from a demonstration of the system. In particular we outline what an SGML DTD is and what SGML documents look like. Our aim is to describe the considerations that are relevant to fonts, the SGML-encoding of non-ascii symbols and characters and the way the Type I fonts needed for the Euromath system (version 2) were generated using Type I versions of the TeX fonts.
