World Emoji Day

Emoji is the fastest growing language in history. Five billion emojis are sent every day, just on Facebook Messenger. They're appearing in some surprising places too. One court judge in England used a smiley face emoji in a document to make it easy to explain the court's decision to children. It's not surprising that there's a day to celebrate emojis, but what do you know about its organisers, the website Emojipedia?
