Abstract
A system, a program storage device and a software method for efficient handling of multiple Unicode formats in the same database on a table level is provided. The routines of the method are used to create a plurality of database tables and specify each table data storage format, including a first table for storing data in a first Unicode format and a second table for storing data in a second Unicode format. The method inputs characters which are encoded in the first Unicode format. When the data should be stored in the second Unicode format, the method uses a conversion routine for transforming some inputted characters into the second Unicode format and stores them in the second table, and then stores unconverted inputted characters in the first table. The first Unicode format is preferably the UCS-2 format and the second Unicode format is the UTF-8 format.
