--------------------------------------------------------------

-So I took a look at this file and it isn't a font bug. The width for character 60 in the
FontDescriptor is 0 and in the embedded font it is 633. So the file really does contain this.-

-What I don't know is what PDF/A actually requires of the font in order to be valid, it's
obviously not the same as what PDFBox's Preflight is doing, but without a copy of the PDF/A
spec, I can't say. Does anybody know?-
