I could not figure out a way, and I am a bit pessimistic. Armed with info from here, I thought the following code might work, but you can see that it did not display the cyclone unicode (but did display the ersatz one that Star Strider recommended).
figure
ht(1) = text(0.2,0.5,char(167));
ht(2) = text(0.8,0.5,char(127744));
set(ht,'FontSize',48,'FontName','Symbola')
