I know it's kind of easy to use the superscript stuff, I've used it before, too. But I really dislike the line spacing effect it causes, where the white space above/below the line is expanded to accommodate the text. I've found that it works better for me to pop open a Word file, insert the symbol I want, like ² or ³, and they copy/paste the character into my text in Creo. Something I found out via a "I wonder if this will work" type of "experiment". It will look weird if the text editor is invoked to modify a note or whatever, but as long as it looks okay in my notes or table entries, I'm fine with that.
