Multibyte Character Sets
Teradata Database supports multibyte characters in object names when the client session
character set is UTF-8 or UTF-16. Refer to International Character Set Support for a list of
valid characters used in object names. In Teradata TPump scripts, double quote multibyte
characters are used in object names.
To log on with UTF-8 character set or other supported multibyte character sets (Chinese,
Japanese, or Korean), create object names shorter than 30 bytes. This limitation applies to
userid, password, and account. The logon string might fail if it exceeds 30 bytes per object
name.
Multibyte character sets impact the operation of certain Teradata TPump commands, as well
as object names in Teradata SQL statements.
Table 18 describes the impact on multibyte character sets on certain Teradata TPump
commands.
