Hi
One of the app team in other dept has a .net application that set ccsid
xmlMsg.characterSet = 1200 before put and the xml data to be put is encoded as UTF-16.
The qmgr the data to be put to has ccsid=1208 and the get application will not use any-convert option and will get the data from the same qmgr that was put to.
IBM info support
http://www-01.ibm.com/support/knowledgecenter/SSFKSJ_7.5.0/com.ibm.mq.ref.dev.doc/q104590_.htm
says WebSphere MQ does not support surrogate pairs.
My question:
if the xml data contain surrogate pairs, will the get application
see any problem with data ?
if yes
Could you suggest how to exclude surrogate pairs in their data? |

MQ does not alter the contents of the message body unless you tell it to convert the data, either at the GET or at your channels.

Based on what you described, the application will get the message unconverted and still in 1200. I doubt if anyone on this site can really answer if your application can handle surrogate pairs.
If your application was to convert the data from 1200 to 1208, it looks like MQ uses CESU-8 to convert surrogate pairs from 1200 to 1208-> https://en.wikipedia.org/wiki/CESU-8
According to that doc, CESU-8 is not an official part of the Unicode standard, so that is interesting.
