The Universal Coded Character Set (ISO/IEC 10646) is approved for standard interchange of MARC 21 records within the specifications in Part 2: UCS/Unicode Environment. The restrictions in these specifications are intended to enable broad interchange among MARC-8 and UCS/Unicode to be possible during the period of transition from a largely 8-bit environment to a UCS/Unicode 16-bit environment. The specifications are built around enabling round trip movement of MARC data between MARC-8 and UCS/Unicode without loss.
