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.
