Better is a comparative adjective.
Even a title page made in Affinity Publisher comes back in from PDF with Small Caps missing, and letter spacing all over the place.
If you have any text that uses ligatures, like fi, fl – you’ll see a question mark or Unicode ‘missing’ glyph in its place.
PDFs directly from Dorico will often import ‘reasonably well’, but weirdly, if you rinse the PDF through MacOS, i.e. combine with pages from another PDF, rotate a page, resave in Preview, etc: then that completely destroys the document. (See Screenshot)
In short: Affinity Suite still cannot be relied upon to import PDFs with fonts in, unless you outline the fonts first (so the computer just understand the character as a ‘shape’, not a text item’); or use EPS or SVG.
