6. Emoji are ideograms and smileys used in electronic
   messages and web pages.
   They are much like emoticons, but emoji are actual
   pictures instead of typographics.
   

   Originally meaning pictograph, the word emoji comes
   from Japanese e (ֆ, "picture") + moji (จࣈ, "character").
   The resemblance to the English
   words emotion and emoticon is purely coincidental.
