Windows live messenger does not have this feature.
But they have feature to disable to whole chat.

I wish there is feature to disable on certain chat contact only.

I love using emoticons to chat with my friend.

But sometime I have to chat with people who has a lot of emoticon that cause the real chat is gone changed by the emoticons.

like makanya (a language in my own) means so

he use makan (eat) as emoticon of a boy eating.

When she writes "makanya" become "makan" and  "ya" where the result is a boy eating emoticon and ya cause me to not understand what she is writing.

I wish there is feature of disabling emoticon in certain chat contact.

Thank you

I don't think this is currently available in a script, but Msg Plus! Live does not have this feature.

Theres been alot of requests on the StuffPlug forums about this feature. But its definately a good feature and it would be great in MsgPlus! Live.
