You should be able to use the

comment to do different fonts. However, the comment summary on the right appears to allow only plain text. For example I did a comment using the

comment and it allowed the Math A and Symbol fonts on the page but not in the comment summary.

However, comments with ##\vec{F} \text{ and } \hat{j}## and other Latex graphics appears to be beyond Acrobat's comment capability.

IIRC, you must have the font installed on the computer to include it in your PDF.

Once you figure out how to reference it (I think you have to use the 16bit UTF character reference), the character is stored in the generated PDF file and is not needed to be on the computer that is reading your file. (similiar to how a line drawing is included in the final PDF)

By the way, the PDF format standard is/was freely available on the Adobe site. Here is a bit of info I downloaded 8 years ago: (the reference is about 32 MB)

Superceded by ISO 32000-1 2008. See also "adobe_supplement_iso32000.pdf"
