When using pdf_info.ps and reporting font usage, the PostScript program does not take Form resources into account, and only reports on Fonts declared as Resources in the Page dictionary. The attached example only uses the ZapfDingbats font in Form resources, and so it is not listed as being used in the PDF file. There may be other cases of resource types which declare fonts, but I don't think so, at present. This is not strictly a PDF interpreter problem, but updating pdf_info.ps will require knowledge of the structures it uses, so I think its best if this is handled by the relevant engineer.

patch
Search annots, forms, patterns for fonts.
Besides the contents, look into annotations to identify fonts used by
the PDF file. Add recursive enumeration of Form and Pattern resources.
