My source file is a PSD with text layers. I'm using Affinity Publisher to import these PSDs into a document, which I'm then exporting to PDF.
This has been working out very well for the most part, but I've discovered that some (not all) inline formatting isn't being preserved during the export to PDF. Italic text is a particular sticking point, as seen in the example below. PDF on the left, APub on the right.
