There are 27 variations of the capital letter A in Unicode (see the confusable list https://unicode.org/cldr/utility/confusables.jsp?a=A&r=None https://unicode.org/cldr/utility/confusables.jsp?a=A&r=None). Redundancy has never been a problem with Unicode. After the decision was made to add the symbols of the original encoding to the list of Unicode characters, they had to add all heart variation, otherwise it wouldn't have been able to be backward compatible. Or alternatively add a color modifier? I'm not sure that would have been a better solution.
