title: Is it possible to store UTF8-mb4 in MongoDB?
body: <p>I have a chat server that stores messages in MongoDB...emoticons (emoji specifically) are giving me grief.</p>
  
  <p>Apparently emoticons/emoji are UTF8-mb4 encoded...can MongoDB store data in this encoding? If it can't stored UTF8-mb4 directly is there some kind of workaround?</p>
