how do I fprintf a power?

Hi, I can't figure out how to get fprintf() to display "r^2" without the "^". I have

fprintf("R^2; %.4f%s%.4f\n", gof.rsquare)

but this displays the "^". How do I fix this?

Using ‘char(178)’ is an option —

gof.rsquare = 0.975;
fprintf("R"+char(0178)+"; %.4f%s%.4f\n", gof.rsquare)

R²; 0.9750

.

alternatively using unicodes (U+00B2 is superscript 2, ..B9 is superscript 1 etc);

gof.rsquare = 0.975;
fprintf("R\xB2; %.4f%s%.4f\n", gof.rsquare)

R²; 0.9750

fprintf("R\xB9; %.4f%s%.4f\n", gof.rsquare)

R¹; 0.9750
