Tilman Hausherr commented on PDFBOX-4859:
-----------------------------------------
What you could try is this: open the file with the PDFDebugger app, then search
for that font in the page resources, go down the tree until you find something
like "FontFile2" (can be 1 or 3). Then right-click and choose "save raw
flatedecode". Save that one. That is just the font, Flate encoded. Then try to
run the java Inflater class on that file and see what happens.
