13.7.8. Character sets and collations

DB2 for i only supports a single collation per index or foreign key constraint. A foreign key constraint must have the same collation as a primary key constraint, if one exists..

Character sets and collations supported by IBMDB2I are described in the list below. IBM i 6.1 is required for the most comprehensive collation support. Note that Chinese, Japanese, and Korean character sets are converted to UTF-16 for storage in DB2 for i; utf8_general_ci is converted to UCS2 for storage in DB2 for i.
