patch 7.4.1629

Problem:    Handling emoji characters as full width has problems with
            backwards compatibility.
Solution:   Remove ambiguous and double width characters from the emoji table.
            Use a separate table for the character class.
            (partly by Yasuhiro Matsumoto)
