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 (B035-1125) for a list of valid characters used in object names. If multi-byte characters are used in object names in Teradata MultiLoad script, they must be enclosed in double quotes
The following table shows how multibyte character sets impact the operation of certain Teradata MultiLoad commands, as well as object names in Teradata SQL statements.
