When you store multilingual data in a DB2 UDB database, Unicode is often the only encoding that adapts to the entire range of data. DB2 can store and process Unicode data, but its sorting function is limited to binary ordering and three cultural sorts. In addition, a database can have only one collation, which is determined when the database is created. These sorting restrictions are an obvious challenge fo
