The Oracle Solaris 11 core locales are as follows:
zh_CN.UTF-8
zh_TW.UTF-8
en_US.UTF-8
fr_FR.UTF-8
de_DE.UTF-8
it_IT.UTF-8
ja_JP.UTF-8
ko_KR.UTF-8

Core locales have better coverage at the level of localized messages than the locales available for additional installation. Oracle Solaris OS components such as Installer or Package Manager are localized only in core locales while localized messages for third-party software such as GNOME or Firefox are often available in more locales.
All locales in the Oracle Solaris environment are capable of displaying localized messages, provided that the localized messages for the relevant language and application are present. Additional locales including their localized messages can be added to the system from the installation repository by modifying the pkg facet properties.
