Why Use OpenType?
OpenType is a cross-platform format that eliminates text reflow, character substitution, and kerning elimination issues associated with sharing documents between Mac and PC systems. Adobe and Microsoft worked together to develop this powerful format for digital typography.
The design stability of OpenType might be enough to justify investing in an updated type library, but the new format offers more. Its expanded character set provides foreign language support and advanced typography options. If you translate documents, using OpenType allows you to maintain typestyle consistency in nearly all the world’s languages, including special punctuation and currency symbols.
Each OpenType font contains as many as 65,000 character shapes, or glyphs, including old-style figures, true small capitals, fractions, swashes, superiors, inferiors, titling letters, contextual and stylistic alternates, and a full range of ligatures. Most postscript fonts were limited to 256 glyphs. To use swash characters, for example, a second font of alternates was required. Using Adobe CS3 or newer software allows easy access to OpenType typography features through pull-down menu selections and automatic settings.
