WorldScript

WorldScript was the multilingual text rendering engine for Apple Macintosh before OS X was introduced.

Starting with version 7.1, Apple unified the implementation of non-Roman script systems in a programming interface called WorldScript. WorldScript I was used for all one-byte character sets and WorldScript II for two-byte sets. Support for new script systems was added by so-called Language Kits. Some kits were provided with foreign versions of the system software, and others were sold by Apple and third parties. Application support for WorldScript was not universal, since building in support was a significant task. Good international support gave a marketing edge to word-processing programs such as Nisus Writer and programs using the WASTE text engine, since Microsoft Word prior to version 2001 was not WorldScript aware.

In 8.5, full Unicode support was added to Mac OS through an API called ATSUI. However, WorldScript remained the dominant technology for international text until OS X, because of limited application support for ATSUI.
