Currently,
Emoji.exists?only checks if the alias name exists usingEmoji.aliases_values.include?(name). This leads to incorrect false returns for certain variations.For example, the emoji
waving_handhas an aliaswave.Emoji.exists?("waving_hand"),Emoji.exists?(":waving_hand:"), andEmoji.exists?(":waving_hand:t2:")all return true.Emoji.exists?(":wave:")andEmoji.exists?(":wave:t2:")return false, while onlyEmoji.exists?("wave")returns true.This PR attempts to resolve this by replacing the alias with the original name and then checking if the emoji exists again.
