WorldScript

WorldScript was developed by Apple Computer to support the use of foreign languages and character sets in classic Mac OS version 7.1 and later.

Features
WorldScript is comprised of the WorldScript I and II extensions, as well as individual foreign language scripts and keyboards, which are installed into the System file. It is not an application program; it enables multilingual features in existing classic Mac OS applications and regulates how various scripts interact with each other.

History
WorldScript was introduced in 1992 with System 7.1, which was localized into 35 languages: Language Kits were individually available for Arabic & Persian, Chinese, Cyrillic, Hebrew, Indian, Japanese, and Korean. Updaters were freely provided by Apple to make previously purchased Language Kits compatible with Mac OS 8. WorldScript and all available Language Kits became a standard part of Mac OS 8.5, which was released in 1998.

Deprecation
Mac OS X replaced WorldScript with Unicode support. It is also used in iOS and its derivatives. Mark Davis, the co-author of KanjiTalk and WorldScript, is now the co-founder and president of the Unicode Consortium.
