I think the bug is in the PDF, it looks like the # is escaped, and shouldn’t. It might be that some apps like Acrobat may unescape this, but that seems wrong to me (it would break URLs that are correct). Unfortunately I cannot check directly in the PDF data whether this is true, as it seems the link is fully encoded in the page data, and not included as a plain annotation dictionary. There is a small possibility that it’s Apple’s PDFKit that escapes the #, which would be wrong, and nothing we can do about. The bug is certainly not in our code, we just pass on the URL that we get receive from PDFKit as it is, which is exactly what we should do. It’s weird that in some instances it works, and not in others.
