Whenever you paste code into Office Communicator, it decides to convert half of your code into emoticons. I'd like to prevent this from happening, so the other side can read the code, and copy it as well.
There is an option to turn off showing emoticons in your conversation window, but I don't think this affects the messages you send.

If the code isn't too sensitive you could use a service like pastebin and send the URL via IM instead.
