Using MQ Client for .NET with C#. Does anyone know how to write a string containing french characters properly into the queue. When I attempt to add the string, the french characters are replaced by invalid characters. For example, when I add the string "My name is Frédéric", it appears as "My name is F.r.0.d.0.r.i.c.". I get spaces and my french characters are converted. Any ideas?

Unicode is a double-byte character format.
.NET strings are Unicode strings.
Those aren't spaces.

Yes, I aware of the unicode, but how do one convert a unicode french string that can be used to write to the queue and appear properly.

The only thing you have demonstrated is actually broken - or at a minimum "not working the way you think it does" - is the thing that is displaying your string as "My name is F.r.0.d.0.r.i.c.".
Everything else, including your code that writes the message AND MQ, may be working just fine.

Yes, that corrrect, writing to the queue is not the problem, the string I have and what actually gets written is not the same and it causing a problem. The client receiving my message received what is written on the queue and not the original string I sent.
I was hoping someone who already attempt to write a unicode french string to a message queue can tell me how they did it using C#.

Please post the output of amqsbcg against a message that your program wrote to the queue.
Again, you haven't shown that your writing code is doing the wrong thing.
All you've shown is that the reading code is either reading the message wrong (as plain text instead of unicode) or is displaying the message wrong.
And if you search here for ".NET" and "Unicode", you might find some helpful hints, too.

Below is a sniplet of the code that writes a message to the queue (Note I'm now converting to UTF8:
string sNewMessage = "Frédéric";
UTF8Encoding utf8 = new UTF8Encoding();
byte[] encodedBytes = utf8.GetBytes(sNewMessage);
sNewMessage = utf8.GetString(encodedBytes);
int openOptions = MQC.MQOO_OUTPUT;
MQQueue inputToDAADQueue = queueManager.AccessQueue(edtInputQueueName.Text.Trim(), openOptions);
MQMessage messageToSend = new MQMessage ();
messageToSend.WriteBytes(sNewMessage);
messageToSend.Format = MQC.MQFMT_STRING;
MQPutMessageOptions pmo = new MQPutMessageOptions();
pmo.Options = MQC.MQGMO_CONVERT;
inputToDAADQueue.Put(messageToSend, pmo);
inputToDAADQueue.Close();
queueManager.Disconnect();
The output from command aqmsbcgc in my DOS windows is:
'Fr?d?ric '

For the third time, there is no evidence that your WRITING code was WRONG. So why did you change it?
And you decided not to post the IMPORTANT part of the amqsbcgc output, which is the BYTE values.
Let me try, one more time.
You need to determine if the byte values of the message data ON THE QUEUE are wrong.
This will tell you if the problem is in the code that is WRITING the message, or in the code that is READING the message.
Until you do that, you don't know where the problem is.
And, again, this exact problem (except for the fact that your Unicode data is French characters) has been discussed here before. It is worth your time to look for that previous discussion.

The output from the DOS windows displays this
00000000: 4672 E964 E972 6963 'Fr0d0ric '
Is it possible the DOS windows cannot display these characters? When I export the output to text file and open it in notepad, it displays properly.

The unicode value for é is 00E9 and the corresponding ASCII value is E9 as well (source = MSWord)
So from what we can see your message is correct on the queue. However the DOS value for it might be different. Remember to look up your correspondance tables and give us the CCSID of the message.
Looks to me you have an ANSI => DOS conversion problem (I don't think amqsbcg does the browse with the convert option...)

I wish I had a dollar for every time I had to deal with something like this.
Look at the data in hex and verify that the hex representation is what it is supposed to be. As far as displaying the characters the way you want them to be, that is purely a function of what tool you are using to display the data and whether or not it is codeset aware. It is also a function of what codesets and/or fonts are available on the machine. There has to be a way of setting the codeset/font for whatever display tool is being used.
