Multibyte language support on IBM DB2

If you support multibyte languages, you must verify database property settings.

If you support multibyte languages, the IBM® DB2® database must originally be created as UTF-8. If the database was not originally created as UTF-8, it cannot be changed afterwards.

The string_units database parameter must be set to CODEUNITS32. This parameter specifies the default string units that are used when defining character data types and graphic data types in Unicode databases.
