My iphone won't let me post emojis on facebook?

I want to be able to post emojis on facebook status's but they don't show up. Why? How can I make them show?

They Are Not Mobile Compatible Thats Why They Don't Show Up On Your Phone When You Visit The Computer You Should See That They Show But On Mobile you Won't See it

Yeah what he said. But even on computers you will only get very limited emoji's, and even then, you have to type it yourself like ^_^, or. You can get more emoji's that you don't have to type, by searching (if you have mozilla firefox) in the add - on store for extra emojis for facebook
