If you use Solaris Live Upgrade with multiple CDs to install the Solaris 9 12/03 release, the Languages CD installs all languages by default.
After the installation, if you log in to the system in a locale that is different than the locale you selected during installation, garbled characters might be displayed. After you log in to any of these locales, the English locale is displayed.
Workaround: During installation, select the custom install option. Uncheck any languages that you do not want to install during the Languages CD installation.
