        Length in grapheme units.
        If $length  is given and is positive, the string returned will contain
        at most $length grapheme units beginning from $start (depending on the 
-       length of string). If $string is less than or equal to $start grapheme

        that many grapheme units will be omitted from the end of string (after the
        start position has been calculated when a start is negative). If $start
-       denotes a position beyond this truncation, an empty string will be returned. 
+       denotes a position beyond this truncation, &false; will be returned.
