Superscript in GUI Text

It is possible to add superscript to a GUI text? For example I need to say Square Feet (ft^2) or Cubic Kilometers (km^3) etc.

Thank you!

While Unity GUI has no support for different fonts/styles in a single text, this specific case can be solved by using the appropriate Unicode superscript characters, Like this: ft, km.

You just have to use a font which includes those characters, or, if you are using Unity 3, use dynamic font rendering.
