I’m having a problem with the correct display of PDFs on an iPhone in the resident OJS PDF viewer. When I use some fonts to build the galley PDF file, the PDF displays as full of nonsense symbols - but only within the resident viewer on the iPhone. It displays just fine in the resident viewer on my desktop and it displays just fine when downloaded on the iPhone.
Hi,
It is probably this same issue: [OJS] pdfJsViewer rendering problems with Safari 10.1. · Issue #2557 · pkp/pkp-lib · GitHub (original PDF.js issue safari 10.1 - bad fonts and italics · Issue #8231 · mozilla/pdf.js · GitHub)
The last comments in the PDF.js issue suggest that the new Safari version would fix this, but I can not confirm this.
