Emoticon keyboard on iphone, not emoji How to have a keyboard that presents shortcuts for common ascii emoticons?

I specifically do NOT want anything that uses the emoji unicode symbols. But instead a keyboard that provides shortcuts for the standard emoticons such as :-), :-(, ;-), B-), :-*, &lt;3, and so on.

Update: so far, it seems there is no way to do what I ask for. So I asked a more specific question asking for SMS apps that support ASCII emoticons.
As Apple doesn't allow for third-party keyboards outside of apps, you'd have to find (or make) an app that does what you want and design your own keyboard to do that.
