A joint project between Adobe and Microsoft to produce a hybrid between Type 1 and TrueType fonts, with additional features. Fonts consist of one file, ending in .otf and can contain both Latin and non-Latin characters, expert and extended characters, and additional styles such as old-style figures, small capitals etc. The same file can be used on PC or Macintosh. Built into Windows 2000 and XP, and available on earlier versions of Windows via Adobe Type Manager.
