Solaris 10: The new localeadm command allows you to change the locales on your system without reinstalling the OS or manually adding and removing packages. This command also allows you to query your system to determine which locales are installed. To run the localeadm command, you must have superuser privileges or assume an equivalent role through role-based access control (RBAC).
For more information, see the localeadm(1M) man page.
