You can still use this type of emoji on facebook, but just be aware that they may be rendered differently depending on the viewer's browser/device/OS. If both the Facebook emoji and the raw unicode symbol are the same, then this means that facebook doesn't have it's own particular symbol, and so the web-browser's version of the emoji will be rendered. Each of the items you see above has 3 sections: the first is the emoji as displayed on facebook, the second is the raw unicode symbol which is used to create that emoji, and the third is a list of tags which you can use to search and filter the emoji collection.

It's just a handy cheatsheet that some guy made for facebook emojis.
