ID CS3 export to PDF - how to get superscripts into bookmarks ?

Question

I'm exporting my InDesign (CS3 Design Standard) file to PDF, and the headings are all nicely showing up in the bookmarks, but the superscript chars in my headings (such as the trademark symbol) are showing as regular chars in the resulting PDF bookmarks.
Anyone know if it's possible to get superscripts into the PDF bookmarks? Either directly from InDesign's export function or after-the-fact w/Acrobat?
I'm using Acrobat 7.0 Standard on Win XP, but if this is do-able with Professional or a later version, I'm open to upgrading.
(I asked the same question in the InDesign forum, and it was suggested that I ask here in the Acrobat forum.)
Many thanks,

>superscript chars [..] (such as the trademark symbol)
There is some dispute over a trademark symbol being superscript or not. In some fonts it is, in others not. Therefore, for some fonts you need to apply "superscript" and in others not.
>[..] showing as regular chars in the resulting PDF bookmarks
That's the way it is. You cannot apply formatting to bookmark text. You
i can
change the font (I seem to rembember), but that doesn't help -- it's a global change.
If you desperately positively need some characters to be in superscript, check the character map for (I think) Arial Unicode. There is a tiny set of characters that has a superscript form: ¹²³ -- but do check if they appear the same in Acrobat.
