Error in state of SceneNode

I am trying to display values of data points on a plot:

for i = 1:size(Nodes, 1)
    txt = sprintf('$T=%.1f%c$C', T(i), char(176));
    text(Nodes(i,1), Nodes(i, 2), txt , 'Interpreter','latex');
end

But I keep receiving the following error:

Warning: Error in state of SceneNode.

String scalar or character vector must have valid interpreter syntax:

$T=100.0°$C

I am not sure how to fix this. Can anyone please help?

txt = sprintf('$T=%.1f^{\\circ}$C');

This will not be an actual degree symbol, but it is close.

The LaTeX interpreter does not support characters outside of the range 0 to 127. And unfortunately does not support \usepackage to bring in packages that have real degree symbols.

I tried using it but I still get the same error.

I forgot we were within sprintf(). I have corrected the command.
