If you have the actual Acrobat program (not the reader alone), you can probably make changes, unless the colleague locked down the file. I guess there are several PDF editors (which I found just now by googling "PDF editor"), but I don't know if any are free, or how well they work.

Probably the footnotes use a different font. On Apr 27, 2007, at 3:12 PM, David J. Peterson wrote:

Roger doesn't know what the right font would be. Is there any way to look inside a PDF and find out what fonts it actually requests? I imagine that's possible if you have Acrobat itself, but are there any free/open source tools for that? (I've also run into a few PDFs where either the characters didn't show up right, or a dialog box came up saying I needed to install certain fonts, which makes me grumble just a little bit, since I thought the point of PDF was to be able to distribute formatted text without worrying about the specific fonts and programs the receiving end has.)
