Greek astrology

I think I had somehow assumed that the symbols used in Greek Horoscopes had already been encoded, but it seems not.
The four signs used to mark the principal corners (ascendant, etc) of the horoscope diagram are shown in the attachment, taken from

http://www.skyscript.co.uk/greek_horoscope.html

These four signs should be encoded along with the zodiacal signs U+2648 to U+2653.
Perhaps they are already in the pipeline ?
