Apple's WorldScript permits the use of multiple languages and scripts on one document on the Mac.

WorldScript is comprised of both the WorldScript I extension and WorldScript II extension, as well as individual foreign language scripts and keyboards, which are installed into the System file. It is not, however, an application programme; but it enables multilingual features in application programmes.

WorldScript regulates how various scripts interact with each other.
