Unicode provides a unique number for each character (text or symbol), across platforms, programs, and languages, ensuring that it is displayed consistently by every computer. The Unicode Standard has been adopted by such industry leaders as Apple, HP, IBM, Microsoft, Oracle, SAP, Sun, Sybase, Unisys, and more. Unicode is required by modern standards such as XML, Java, JavaScript, LDAP, CORBA 3.0, WML, etc. It is supported in most operating systems, all modern browsers, and many other products. Version 5.0 contains the knowledge gained from many years of worldwide implementation experience, and has been enhanced significantly: the text incorporates fifteen years of user feedback, provides thorough answers to the many questions users of Unicode have raised, and is much more accessible--with greatly improved figures and tables, and with the text revised for clarity. Annexes contain 50% new material and provide specifications for important processes such as text normalization and identifier usage.
The Unicode Consortium is a non-profit organization founded to develop, extend and promote use of the Unicode Standard, which specifies the representation of text in modern software products and standards. The membership of the consortium represents a broad spectrum of corporations and organizations in the computer and information processing industry. The Unicode Consortium actively cooperates with many of the leading standards development organizations, such as ISO/IEC JTC1, W3C, IETF, and ECMA. The Consortium is based in Mountain View, CA, with members located around the world.
