Question : Adobe PDF bookmark font is gibberish

We have a Publishing team of 5 graphic designers, working on identical platforms (Windows XP Pro) with identical software Adobe CS3 (including Acrobat Pro 9). One of the designer's bookmarked PDFs are randomly problematicher bookmarks show up as gibberish (symbols, etc.) instead of a readable font. As noted, this only happens occasionally. In researching this, I understand that the font used in Adobe PDF bookmarks is a "system font", but which system font I don't know. Can someone help explain to me: which system font Adobe's PDF bookmarks use, is it always the same system font used every time, and why this problem only shows up seemingly randomly on just 1 of the 5 graphic design systems, and how I can resolve it?
Thanks in advance,
Andrea

Answer : Adobe PDF bookmark font is gibberish

Could be a number of issues such as a corrupt or missing system font. Sounds like you need to standardize the fonts your designers are using, and then replace all the fonts on that designer's machine. It would be much easier than trying to identify and isolate the font in question.
