The application of layout features to one or more characters may change the positioning, or substitute a different glyph. For any character, there is a default glyph and positioning behavior. OpenType layout features can be used to position or substitute glyphs. One glyph can also represent multiple characters, as in the case of the "ffi" ligature, which corresponds to a sequence of three characters: f, f and i. One character may correspond to several glyphs the lowercase "a," a small cap "a" and an alternate swash lowercase "a" are all the same character, but they are three separate glyphs. Glyphs are the specific forms that those characters can take.

Characters are the code points assigned by the Unicode standard, which represent the smallest semantic units of language, such as letters. Although the exact intended sizes vary by family, the general size ranges include: caption (6-8 point), regular (9-13 point), subhead (14-24 point) and display (25-72 point).Ĭentral to a discussion of OpenType feature support lies the distinction between characters and glyphs. Called "Opticals," these variations have been optimized for use at specific point sizes. Several of Adobe's OpenType fonts include four optical size variations: caption, regular, subhead and display. Historically, some of the highest quality typefaces have included different designs for different print sizes.

OpenType fonts may contain more than 65,000 glyphs, which allows a single font file to contain many nonstandard glyphs, such as old-style figures, true small capitals, fractions, swashes, superiors, inferiors, titling letters, contextual and stylistic alternates, and a full range of ligatures. OpenType significantly simplifies font management and the publishing workflow by ensuring that all of the required glyphs for a document are contained in one cross-platform font file throughout the workflow.

In the past, a typical Western PostScript font was limited to 256 glyphs, forcing you to install and manage two or more style-related fonts in order to access "expert set" characters. OpenType fonts can be installed and used alongside PostScript Type 1 and TrueType fonts. Feature-rich Adobe OpenType fonts can be distinguished by the word "Pro," which is part of the font name and appears in application font menus. OpenType fonts can include an expanded character set and layout features, providing broader linguistic support and more precise typographic control. otf suffix in the font file name, while TrueType-based OpenType fonts have a. OpenType fonts containing PostScript data, such as those in the Adobe Type Library, have an. The OpenType format is an extension of the TrueType SFNT format that also can support Adobe® PostScript® font data and new typographic features.

The two main benefits of the OpenType format are its cross-platform compatibility (the same font file works on Macintosh and Windows computers), and its ability to support widely expanded character sets and layout features, which provide richer linguistic support and advanced typographic control. Adobe has converted the entire Adobe Type Library into this format and now offers thousands of OpenType fonts. OpenType® is a cross-platform font file format developed jointly by Adobe and Microsoft.
