PDF Many complaints about PDF support, mostly:
- Evince doesn't support non-ascii characters in PDF forms, this is a
major problem for many people.
- Some PDF forms refuse to work with anything but Acrobat Reader
although they may work just fine with Evince, faking a reader's identity might be a solution here.
- Incomplete support for PDF 1.7.
The forms problem may be a lack of XFA support. [1] On the one hand, XFA is considered proprietary and is not included in the ISO standards applying to PDF; and yet on the other hand PDF 1.7 considers XFA effectively mandatory. That's confusing.
Aside from XFA, there are also limitations Evince has with XMP in PDF. A Simple-Scan document by default is PDF/A, and the creation and modification dates are wrong in Evince, related to lack of XMP support Poppler. [2] That's an unfortunate sequence, because it's good and appropriate to use PDF/A for long term preservation of documents. But then, oops, Evince can't be trusted to show the document's creation date.
