Here is how you do it folks... you add a profile question..
set it as as single choice dropdown
then copy and paste this in the values area
Aries
Taurus
Gemini
Cancer
Leo
Virgo
Libra
Scorpio
Sagittarius
Capricorn
Aquarius
Pisces
then finish the question and save.
Now for the symbol addition...
the bad part is that you have to add these one at a time in the language area. You CANNOT paste these directly in the question value (although that would easy) it wont work because due to the use of html entities and other sanitation of the values field, the code will show in the dropdown instead of the symbol. So you HAVE to do this one at a time in the language admin and then it will covert on the dropdown to the symbol.
so in admin language:
Search And add code after the name

Virgo <span style="color: #F5A9A9;font-weight:bold;">♍</span>
Libra <span style="color: #F5A9A9;font-weight:bold;">♎</span>
Scorpio <span style="color: #F5A9A9;font-weight:bold;">♏</span>
Sagittarius <span style="color: #F5A9A9;font-weight:bold;">♐</span>
Capricorn <span style="color: #F5A9A9;font-weight:bold;">♑</span>
Aquarius <span style="color: #F5A9A9;font-weight:bold;">♒</span>
Pisces <span style="color: #F5A9A9;font-weight:bold;">♓</span>
easiest way is to just copy and paste the same code to each and just change the number, they are sequential.
