Given that CONVERT(YES) on the channel is successfully converting the message, and you have confirmed the message ccsid is 37, and the square bracket is the correct hex code BA, it appears the issue is with conversion on DP.
Can you dump a message using amqsbcg? This will show all the MQMD fields and the raw unconverted RFH and data. There could be a lurking ccsid issue that is upsetting DP. |
We ran the amqscbcg. For this test, the convert flag is YES st on cluster receiver channel is on. I am unable to share the data part but can share the header with some info masked.

Please see Encoding : 546 CodedCharSetId : 819 from the amqsbcg program output. The Z/os is using "037" though. We ran both with channel conversion ON and OFF on the request cluster channel. But did not see any difference in the amqsbcg output of the encoding. So I am bit confused. |
After changing the value of CONVERT, did you restart the channel? (ie. this is not a dynamic setting for channels that are running at the time)
Based on the MsgId, it appears the message is from z/OS. It is has been converted from and EBCDIC ccsid (eg. 37, 500) to 819. It is MQHRF2 format, so there will be a sequence of one or more MQRFH structures in the Message Data, followed by a payload data string. Each of the MQRFH contains a CCSID field. Can you provide the message data, with some indicative characters in the MQRFH strings so that we can check if they are ASCII or EBCDIC.
I suspect that MQ is converting everything correctly, but it pays to check.

Yes, We did.

Is there any way I can PM you? Not sure the data can be shared here. |

You can redact the data to share here, or you can follow my suggestion of checking the CCSID and data in each of the MQRFH structures.
