error: unterminated string literal

Actually, you did add those mysterious space characters to the end of the bookmark names. This is a common issue, and in fact it's so common that I've written a tool to [url=http://www.pdfscripting.com/public/programs/downloadsearch.cfm?searchtype=simple&searchmode=cat&keywords=recent&sortby=name&cat=Automation%20Tools]clean up bookmarks[/url]. The characters that are being appended are a LineFeed/Carriage Return combination because you hit the return key after entering the bookmark. I know, it seems like a pretty dumb way to make a user interface, but that's Acrobat for you. The right way to enter a bookmark is to click off it.It's possible that the line feed is also causing an unterminated string literal error, since convering the bookmark into code would cause a line break in the middle of a string.
