Subscripts and superscripts in Unity new GUI

Is it possible to display subscripts or superscripts in the new GUI system?

Try using unicode.
For example, “\u207F” is superscript of n, and “\u2091” is subscript of e.

You can do that from the script. An example from my project:
gText.text= string.Format(“g = {0:F1} m/s²”, mass);
You may copy and paste (O₂) or (O²) inside the " " and then customize it.
