i5/OS™ supports ISO/IEC 10646 Universal Coded Character Set 2, Level 1 (UCS-2, Level-1). IBM® DBCS-capable display stations, however, do not support UCS-2 Level-1 data.
If you are designing an application to handle UCS-2 Level-1 data for display on an IBM DBCS-capable display, you must convert the data to a mixed-byte CCSID before sending the data to the display station.
