MQ window to Unix special chars

Question

I am using .net client to post mesages to MQ server which is hosted on Unix. It is added some control character before the messages. Like below

**^CD**<request> 

The Queue connection is through SSL Table channel connection. The code i am using is

MQQueueManager queueManager = new MQQueueManager ; 
int openOptions = MQC.MQOO_OUTPUT + MQC.MQOO_BIND_NOT_FIXED + MQC.MQOO_FAIL_IF_QUIESCING; 
MQQueue Queue = queueManager.AccessQueue("TestQueue", openOptions); 
MQMessage queueMessage = new MQMessage(); 
queueMessage.WriteUTF("<request>"); 

MQPutMessageOptions MessageOptions = new MQPutMessageOptions(); 
Queue.Put(queueMessage, MessageOptions); 

please let me know what cause this special chars

Answer 1

From IBM's own doco on WriteUTF:

This method takes an ActiveX string and writes it into the message data buffer at the current position in UTF format. The data written consists of a 2-byte length followed by the character data. DataOffset is incremented by the length of the string if the method succeeds.

If you don't want that length, consider using WriteString instead (follow that doco link above and just go up a couple of lines in the navigation pane)..
