- jchw 4y agoThe structure however is still largely ASCII text. It needs to be treated as binary of course, due to the use of offsets everywhere and the fact that the xref table is hardcoded to have a specific length per xref in bytes. But if you look at a lot of simple or old PDFs, it's not hard to find some that don't use any binary encodings.
