I was surprised Facebook does not tell the users about their “smilies” list, or the users are just happy with the plain text when chatting. A talk with a friend last day had urged me to search for the “official” Facebook emoticons / smilies list, and somehow I some hits.
I have managed to compare the results, and because they are hardcoded text, i was forced to try them one by one. I then compiled the images and the corresponding text, and uploaded it here so it’ll be easier for me (and for you) to refer to it. Seems this is an outdated list, because my friend was able to use a “like” emoticon and a couple of other smilies that are not listed here. I’ll just update this post when I found the new text codes. If you know it, you can also share by commenting here.
