The Unicode standard has been adopted by industry leading companies such as Apple, HP, IBM, Just Systems, Microsoft, Oracle, SAP, Sun, Sybase, Unisys, and many others. Unicode is needed to support modern standards, such as XML, Java, EcmaScript (Java Script), LDAP, CORBA 3.0, WML, etc. and is ISO/IEC compliant. There is an official way to implement 10646. This occurs in many operating systems, all modern browsers, and many other products. The emergence of the Unicode Standard and the availability of its supporting tools are among the most important recent worldwide software technology trends.
Incorporating Unicode into client-server or multi-dimensional devices and websites can result in significant cost savings over using traditional tools. Unicode allows a single software product or single website to be used across different platforms, languages and countries without re-engineering. This allows data to move through different systems without any hindrance.
