Installing and enabling the IBM z/OS conversion environment and services

Create an IMAGE member in SYS1.PARMLIB using the CUNMIUTL utility.
Copy the CUNIMG01 member from WORK.IMAGE to SYS1.PARMLIB.
The CUNIMG01 member is loaded into z/OS using the SET UNI=01 command.
The DISPLAY UNI, ALL command displays the current active image and the character set conversions defined for that image.

To enable Unicode support, set the USEIBMUNICODE configuration parameter to Y. The USEIBMUNICODE is specified in the SYGWMCST macro in the SYGWXCPH customization module. The Server Option uses the newly defined unichar, univarchar, and unitext internal datatypes and performs conversions between UTF-8, UTF-16, and other CCSIDs.

For information on installing Unicode support for IBM z/OS, see “Support for Unicode Using Conversion Services” (SA22-7649-01).
