Came here to mention puppeteer since I didn't see it in the author's suggestions. I developed a huge script at my last job which processed PST files into PDFs, and it relied heavily on wkhtmltopdf. After discovering the issues surrounding font embedding and lack of interoperability with windows/adobe acrobat (when redacting) I was tearing my head out trying to figure out how to get it to work. In the end, I chalked it up to being a limitation of how the program handled fonts, and looked for an alternative. After discovering puppeteer and dropping it in (replacing wkhtmltopdf), basically all the problems I was having with fonts disappearing were solved. Did not look back.
