It does not work in 'Windows' machine! There is a roundabout to tackle this problem.
figure(1);
x = 1:5;
y = 1:5;
z = round(2*ones(1,5));
% plot3(x, y, z, 'ok');
plot(x, z, 'ok');
text(1.5,1.5,[char(0x2B2E) char(0x2B2C) char(0x2B2F) char(0x2B2E) char(0x2721)],'fontname','ZapfDingbats','fontsize',20); % char in hexadecimal code
