Enabling Unicode data conversion by z/OS

z/OS® can provide support for the conversion of Unicode data (either UTF-8 or UTF-16) to any of the EBCDIC CCSIDs, currently supported by CICS®. If you intend to make use of this capability, you must enable the z/OS conversion services and install a conversion image which specifies the conversions that you want CICS to perform. See Selecting conversion images for more information.

Important

z/OS Support for Unicode must be activated before you start CICS.

Refer to the instructions in the z/OS manual Support for Unicode: Using Conversion Services SA22-7649. (Level -02 of that publication relates to z/OS release 1.4), to find out the steps needed to set up your system and configure a suitable conversion image.

If z/OS conversion services are not enabled, a message is issued by CICS to indicate this. That message can be suppressed if you do not need these services.

To discover the status of z/OS conversion services after an IPL, use one of these commands:

/D UNI
To show whether z/OS conversion services were enabled.
/D UNI,ALL
To show whether z/OS conversion services were enabled, and which conversions are supported by the system.

from an MVS™ console. For details of this, see the z/OS Support for Unicode: Using Conversion Services manual SA22-7649
