The STIX Fonts have been designed to work with all web browsers, word processors, and other scholarly communications software, as well as all general purpose software.
The Fonts are based on the Unicode™ standard for character representation. By expressing all characters with their Unicode value, programs that you use will select the correct glyph for representation.
A character is a unique letter or symbol that is defined by its Unicode value.
Not all Unicode values are included in the STIX Fonts, but there is extensive coverage of Latin alphabets, Greek, and Cyrillic.
The Font contents were assembled from a list of every character/glyph required for publication in the journals of the participating STI Pub companies. Every scientific discipline is represented in this list, as well as many other fields from the arts and humanities.
A glyph is a representation of a character in a particular style. Examples of glyphs of the character “Latin small a” include a (regular weight, upright), a (regular weight, italic), a (bold weight, upright), and a (bold weight, italic).
Most of the glyphs in the STIX Fonts have been designed in Times-compatible style. Times was first designed under Stanley Morison's direction by Victor Lardent at The London Times in 1932. Many variations of this design have been produced since the original.
In addition to Times-compatible glyphs, some portions of the STIX Fonts include other design styles such as sans serif, monospace, Fraktur, Script, and calligraphic.
