CCSID values defined on i5/OS
This table lists the coded character set identifiers (CCSIDs) that
are defined on i5/OS.
Supported CCSID mappings
With V5R4M0, the operating system can dynamically create CCSID mappings on demand by using Unicode. These CCSID mappings are predefined for better performance or mapping customization.
Associated CCSIDs
This table shows the associated CCSIDs for a given CCSID value and encoding scheme.
Encoding schemes for the CCSIDs
This table shows the encoding scheme values (from Character Data Representation Architecture) that are used for the CCSIDs.
