Talking about fancy five stars, besides the vertically split ones there is the "Anarchist star" (a symbol for anarcho-syndicalism)
with a diagonal split in a upper left red half and a lower left black half. Since there are political and ideological symbols encoded
in UNicode, maybe this one is worth encoding as well (probably twice, once as a black and white plain symbol and once as a colourful Emoji).
