Superscript Problem

#1
Trying to get units of metres squared in some text by using the character map code for a superscript 2 - "\u+00b2". It correctly shows what it should be in the text edit box, but on the drawing shows as "?".

The same drawing file correctly displays the superscript 2 on AutoCAD.

Are there any other ways of getting a superscipt in Intellicad? I have Pro version 6.6.82.0

Thanks.
