Renaming Bookmarks

Question

I just finished a project in InDesign which was then exported to PDF to make a slide show of 517 slides, each with a title that was bookmarked by creating a Table of Contents in InDesign.
My problem is that all of the titles were in the form of 000-A[A] where the first three characters were a three-digit number, and the fourth and optional fifth were letters. The ID document was created using Data Merge, and in the original data file there were no hyphens, making some of the combinations difficult to read. I used GREP to add the hyphen with a thin space on either side to achieve the look I wanted before adding the TOC.
After export to PDF I discovered that the bookmarks generated all had little square boxes around the hyphens representing missing glyphs for the thin spaces. I presume this is due the choice of font used by the OS to display the bookmark links, and I don't see any way to control that on my own system, let alone on a remote user system.
I worked around this by removing the thin spaces from the titles and re-exporting the PDF, but I would have preferred to leave them in. Is there any way to run a script in Acrobat, similar to running a find/change in ID, that would go through and automatically rename 500+ bookmarks, removing the unavailable thin space characters while leaving them in place on the page?

Answer 1

Although the project is now out the door, I'd be interested in some hints. I'd say I'm a "literate novice" in that I used to write a bit of Java code now and then, and at least understand the syntax in javascript, and I'm starting to learn GREP for use in ID, so the concept isn't foreign.
Is there a reference on the DVD or something for finding the right names for properties in Acrobat?
Now that I know you can use javascript to alter the file itself, rather than just perform a secondary action, I'd approach this in terms of creating a bookmark array and looping through it looking for instances of the offending characters (thin spaces in this case) and removing or replacing as you go.
While you are being this helpful, is there any way to change the font in the bookmarks panel?
