How to keep superscript in header text xref? It is OK in TOC.

Question

I am updating this generated book:http://www.crystalfontz.com/products/533/datasheets/1704/CFA533-YYH-KC_v1.0.pdf using FM 9, unstructured.
As you can see on the title page, the product name has a superscript "2" in it. Unlike this post http://forums.adobe.com/message/1240012#1240012, I have no problem with keeping the superscript in the TOC.But I have a problem keeping the superscript "2" in the header text
I set up the header text as a separate file.
The "2" correctly appears as superscript in this header text file.
In this header text file, the phrase of text with the superscript "2" is set up as a cross-reference with the cross-reference format definition as "<$paratext>".
On the Master page for each file in the book where I want the header text to appear (for example, in the TOC, Body, Appendix files.), I have a marker for the cross-reference. I can change characters before or after the superscript "2" in the header text file, Update the book, and the header text cross-referenced  in the TOC, Body, Appendix files show the update.
I have the superscript character tag in in the catalog of all the files.I am not using "As Is".
Is this enough information to figure out what the problem is?
If there is a dumb way to set up header text, please let me know. I've been using it this way successfuly for years but can change it, if needed.
Thank you,

Answer 1

Sylvia,
If you need a superscript 2, why do you not just enter exactly that character and don’t both with extra character formats? With Western Windows you would enter the character using Alt+0178.
¹ = Alt+0185
² = Alt+0178
³ = Alt+0179
Other fonts may have all digits available as super- and subscript characters, check with the Character Map utility.
