--------------------------------------------------------------
-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?-
