I notice a lot of applications use the same emoticon set. I guess that they use unicode characters to represent the values. It looks like there is a generic set of images used to display them.
Does anyone know where to find this list (unicode code + emoticon image?)?
The images I refer to: (http://news.en.softonic.com/new-emoticons-added-to-whatsapp-for-android-1)
EDIT: I found the references to the unicode here: http://en.wikipedia.org/wiki/Emoji
Ok. I found a list here. I think it is a complete list.
