Leopard Reference Library: Internationalization
Unicode is an international standard character encoding that contains all the characters needed by the world's commonly used writing systems and a great many less commonly used ones. Mac OS X uses Unicode as its native character encoding because it can represent most of the world's languages in a single, industry-standard character set. Developers can take advantage of the support Apple provides for Unicode text rendering and editing, for locale-sensitive operations on Unicode text, and for converting between Unicode and other character encodings.
