    return tag:upper()
end)

local emojified = emoji.emojify('I :unknown_emoji: :star:', onMissing);

format

emoji.emojify(str, missing, format)

As third argument, emojify takes an handler to wrap parsed emojis. Provide a function to place emojis in custom elements, and to apply your custom styling:

local format = function(emoji)
    return '<img alt="' .. emoji.emoji .. '" src="' .. emoji.key .. '.png />'
end)

local emojified = emoji.emojify("I :heart: :tea:", nil, format)
--> emojified: "I <img alt="❤️" src="heart.png" /> <img alt="🍵" src="tea.png" />"
