The Apple Type Services for Unicode Imaging ( ATSUI ) is the set of services for rendering Unicode -encoded text introduced in Mac OS 8.5 and carried forward into Mac OS X .
5-777: It replaced the WorldScript engine for legacy encodings. ATSUI was replaced by a faster and modern Unicode imaging engine called Core Text in Mac OS X 10.5 (Leopard). It was officially deprecated with Xcode 4.6, which was released in December 2012: "Source code using ATS APIs will generate warnings while being compiled. For 10.8, there will be no loss of functionality but there could be areas where performance will suffer. Programmers are instructed to replace all their ATS code (including ATSUI) with CoreText as ATS functionality will be completely removed in future releases of OS X." ATSUI
10-740: The WASTE text engine , because Microsoft Word prior to version 2001 was not WorldScript aware. Mark Davis had co-founded the Unicode Consortium , co-authored his first major internationalization framework in the form of WorldScript at Apple, became the internationalization architect at Taligent where he designed what became all the internationalization support for the Java Development Kit 1.1, became IBM's Chief Software Globalization Architect, moved to Google to work on internationalization and Unicode, and now helps to choose
15-469: 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
20-460: Was not universal, since building in support was a significant task. In 8.5, full Unicode support was added to Mac OS through an API called Apple Type Services for Unicode Imaging (ATSUI). However, WorldScript remained the dominant technology for international text until Mac OS X, because of limited application support for ATSUI. Good international support gave a marketing edge to word-processing programs such as Nisus Writer and programs using
