"Given that rich text equals plain text plus added information, the extra information in rich text can be stripped away to reveal the "pure" text underneath." "Plain text must contain enough information to permit the text to be rendered legibly and nothing more." "The Unicode Standard encodes plain text." (Above quotes from The Unicode Standard 5.0, pages 18 and 19) It's true that added features can make for a better presentation. Removing the special features shouldn't alter the message. The Unicode Standard draws the line between minimal legibility and special features. Emoji are in The Standard and have, therefore, been determined to be required for minimal legibility. If the emoji repertoire expands and Unicode does not include the new emoji, then Unicode cannot be depended upon to exchange legible textual data. The addition of more emoji to Unicode is inevitable.
