The standard was published in 2007, and is now freely available for download from ITTF website. OpenType version 1.4 was contributed to ISO and became the foundation for the development of ISO/IEC 14496-22 “Open Font Format” standard.

Different applications have differing levels of support for all the OpenType features. OpenType fonts can also include typographic refinements such as true small caps, different styles of figures, and extensive sets of ligatures and alternates, as well as complete sets of accented characters and diacritical marks. This means that an OpenType font may contain multiple alphabets (such as Latin, Greek, and Cyrillic or kanji, kana, and romaji for Japanese use). OpenType fonts can potentially contain many thousands of characters. OpenType, like TrueType, is based on Unicode, the system for encoding all of the world’s writing systems.

The OpenType 1.0 font specification was released in 1997. OpenType is a font format developed jointly by Microsoft and Adobe as an extension of Apple’s TrueType font format.
