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.
I do not use Office Communicator, but if this a matter of the formatting of the text, then one can paste the pure text without formatting by using the free product PureText.
If it is not a matter of formatting, the free utility sanvient can paste text while replacing a regular expression. I do not know this product, but if you define the emoticons via a regular expression, you may be able to edit them out when pasting via this utility.
HovText is another simpler utility that can paste while filtering out text with regular expressions.
