Oh yes like PDFs. Those are so unportable.

Funny thing: I've created many many valid PDFs that many PDF reader implementations cannot render correctly. Most of them I didn't even do intentionally. I sort of think of it as "DF".

Actually, PDF is a 7-bit ASCII format. Yes, there might be some binary content embedded, especially if you use compression and/or encryption, but like PostScript it is a language that you could write in a normal text editor.

Fun fact: In the national German computer science contest (Bundeswettbewerb Informatik) we once got a solution for an exercise, where some fractal image should be computed. The code was entirely written in PostScript. It could be send to a PostScript printer to compute and print the image. There was no restriction to the programming language. The code had to be documented and the language should be somewhat reasonable.
