As we’ve already mentioned, it’s safer and more reliable to use images, not fonts, for emoji in Office documents and Outlook emails.
Just to add more confusion, there are “emoji’s” released which are supplied as standard images not fonts.
Some examples of ‘image’ emojis:
Australian radio network Triple-J released some emoji’s suggested by their listeners.
Finland is releasing a ‘national emoji’ a day in December 2015 including sauna, Nokia phones and ‘headbanging’ music.
