The following example uses dtterm and will start a Japanese terminal emulator. It assumes that the default language is not Japanese, that you are using the Korn shell, and that the locale-specific files have been installed.
From a command line in a Korn shell Terminal window type:
LANG=Japanese_locale dtterm
where Japanese_locale sets the value of the LANG environment variable for the Japanese character set. Refer to your specific platform to determine the value for Japanese_locale.
