The character set identifier (CCSID) that is used to show that a CCSID value for data at this level of processing is not relevant. When CCSID 65534 ( FFFE ) is associated with data, a CCSID value for the data should be obtained from the tagged fields of elements that are at a lower level in the defined hierarchy. For example, a file has CCSIDs tagged for each individual field it contains. If the file is tagged with CCSID 65534, processing is based on the CCSIDs assigned to each individual field instead of the CCSID assigned to the file.
