Error description

• MQRC 2110 (MQRC_FORMAT_ERROR) occurs when converting messages
  due to unconverted format name in RFH2 header
  
  EBCDIC RFH2 header contains UTF8/ASCII
  value in 'Format' field after applying
  the PTF for PM77599.
  If the message is got using the
  MQGMO_CONVERT option, the get returns

  ****************************************************************
  During the get of a message, an RFH2 header is created to
  contain any message properties, and is inserted into the chain
  of headers at the start of the message. If the RFH2 is inserted
  after an RFH1 or RFH2 header, the Format field from that header
  is converted to the CodedCharSetId of the new RFH2 header
  (normally the CodedCharSetId of the Queue Manager) and stored in
  the new RFH2. However, if the Format field is in CodedCharSetId
  1208 (UTF8), an error in the code added by PM77599 causes the
  conversion to fail, and the unconverted value (in UTF8) is
  stored in the new RFH2 instead.
  

Problem conclusion

• CSQMHDRS is updated to prevent the conversion error when
  inserting the properties RFH2 after an RFH1 or RFH2 header in
  UTF8.
