Module:Emoji implements two functions:

emocode 
It takes one unnamed parameter, the name of the emoji, and returns the hex code for the corresponding emoji. If no name is supplied it uses "smiley" as the default (and returns 1f603).
emoname 
It takes one unnamed parameter, the hex code of the emoji, and returns the name for the corresponding emoji. If no name is supplied it uses "1f603" as the default (and returns smiley).

It stores the mapping from name to code in Module:Emoji/data, which internally generates the reverse lookup table from code to name.

Examples

  • {{#invoke:Emoji | emocode | wink}}1f609
  • {{#invoke:Emoji | emocode | grin}}1f601
  • {{#invoke:Emoji | emocode | 8ball}}1f3b1
  • {{#invoke:Emoji | emocode }}1f603
  • {{#invoke:Emoji | emoname | 1f62b}}tired_face
  • {{#invoke:Emoji | emoname }}smiley

	return emotbl[emoname] or emoname
end
