"Emoticon" used to be the general term and was also often applied to smileys in forums (which are more closely related to the kind of custom "emojis" you still find in places like Slack or Twitch). In those cases the term has definitely been superceded by "emoji" but this is due to them being hard to distinguish from real Unicode emojis.
