The S in PDF stands for standardized.

In the printing business there are pdf standards. PDFX

Works for printing man. It's just plotting glyphs to a Cartesian plane.
That is delegating the understanding work to humans.

Don't tell me about PDF files. My client's usually have just the PDF, not the original file format and send them to be translated.

I cannot say no to client's, so my software engineer probably curse me every time I send him these projects.

@brunofontes
Files transformed from original documents to PDFs happen via software and hence all PDFs should me more or less consistent. I'm dealing with a shitty problem. We are aggregating million PDFs from around 100 sources written using pirated tools and stuff. Not just misspelled words, the spacing between letters is inconsistent. Extremely frustrating.
