As Unicode is more and more ubiquitous in everyday life and computing, the number of Unicode locales supported in Unix systems has been dramatically increased over time.

Solaris operating environment is not an exception. Since we added two Unicode/UTF-8 locales at Solaris 2.6 released back in 1997, the number of supported Unicode locales that we added in later releases of Solaris operating environments has been also increased rather rapidly.

With these ever increasing number of Unicode locales, we believe that achieving and also providing a common set of coverages, features, and behavior as much as possible are quite important for our customers to have a seamless user experience on any Unicode locales and also for a guaranteed level of data integrity in character data input/output, presentation, and exchange.

This technical presentation describes the common Unicode locale coverages, features, and behavior definition that we developed for all Solaris Unicode locales. This technical presentation also describes how this definition has been actually realized in the latest major release of Solaris operating environment.
