Plaintext emojis that start with ":" will also match against the shorthand regex but the match won't include the important part of the plaintext emoji. This means some emoji like ":)" won't be matched. To fix this, put the ascii emoji regex first so that the match will be plaintext or otherwise it will fall through to the shorthand match (if there is one).
