If you enable Japanese language support, by default Teradata Database stores:
- Object names in the Data Dictionary using the UNICODE server character set
- User data in Teradata Database tables using the UNICODE server character set.
In Japanese Language Mode, the default server character set for user DBC is UNICODE.
About Using UNICODE to Store User Data
Unicode is a 16-bit encoding of virtually all characters in all current international languages. User data stored as Unicode can be easily shared among clients that use diverse character sets.
For more information about Teradata support for UNICODE, see UNICODE Server Character Set.
