Thank you Libre for the comprehensive explanation. I am no expert, so much of the more technical side of things will go straight over my head. Dealing with fonts in the Affinity suit is one hiccup that I keep encountering. I have downloaded dozens of fonts from Google Fonts to be able to open PDF files that have embedded fonts that I do not have installed.
For example if I want to print a brochure from a PDF file, Adobe will always open the fonts without an issue but APub will almost always require me to download a new font. Is there a way to convert text to curves when opening a PDF in APub?
I realise this is not necessarily an issue with Affinity Publisher, but it is not as user friendly to open/merge/print PDF's as Adobe Acrobat etc. Affinity Publisher is probably "over powered" for the function I am using it for, but I can't justify purchasing Adobe Acrobat Reader for over $200 a year.
