Convert characters call
Use the MQXCNVC (convert characters) call from within a data-conversion exit program to convert character message data from one character set to another. For certain multibyte character sets (for example, UTF-16 character sets), the appropriate options must be used.
No other MQI calls can be made from within the exit; an attempt to make such a call fails with reason code MQRC_CALL_IN_PROGRESS.
See MQXCNVC - Convert characters for further information on the MQXCNVC call and appropriate options.
