The following code display the symbol
CellPrint[TextCell["⥀","Text",FontFamily->"Cambria",FontSize->32]]
Notice that it is not displayed in the Notebook input because the input cell use Consolas font which does not include this unicode symbol according to ANTICLOCKWISE CLOSED CIRCLE ARROW (U+2940) Font Support
I am version 12.0 for Windows. I sent in a question on how to get to Version 12.1. Thanks for all of the help!!
Graphics3D[{Sphere[{0,0,0},1], Text[Style["|⥀>",FontFamily->"Cambira",FontSize->32,Bold],{0,1.1,0}], Text[Style["|⥀>",FontFamily->"Cambira",FontSize->32,Bold],{0,-1.2,0}] }]
I cannot reproduce the issue in V12.1 for Windows.
It is
"\:2940"
What is your default font? Try
Text[Style["\:2940", FontFamily -> "Cambria"]]
Text[Style["\:2940"] puts an empty box on the plot. Is there some way I can get the circle and not the box?
I see the little question mark "?" in a box. Exactly what characters were typed to cause that "?" in a box?
