# Bugs #1072 and #1079 illustrate cases that qpdf-json got wrong. In
# #1072, it was noticed that name tokens containing binary characters
# (using #xx) would generate invalid JSON, even though qpdf's own JSON
# parser would accept it. Also, the JSON spec allows real numbers in
# scientific notation, but the PDF spec does not.
