Change the font?

[jbrockerville]

I have a PDF (which I can't share, unfortunately) that contains emojis that don't display in any viewer nor are they correctly read using PdfPig. I believe that's due to the font used in the PDF. It doesn't have those glyphs. I brutishly changed the font to "Segoe UI Emoji" via MS Word and now viewers display the emojis and PdfPig can read them. Great. But changing the font via Word is a non-starter. That was just to see if that was the problem.

I found and played with the example that copies pages to a new document, added Segoe, but it didn't change the page fonts. How do I do this?

I also found a merge that says:

Adds ability to replace tokens in an existing PdfDocument before parsing pages or copying them to a PdfDocumentBuilder

Is that something I can do? Replace the font resources before parsing? Because that would be even better! But how do I do that?

Thanks!
