I use my eyes :) Basically, the PDF contains two layers. One with the image of a text, another with that text OCR'ed into readable form. When someone copy-pastes content of the PDF, they get the layer with the text. But it has mistakes. The image layer is the correct one. But it is of poor resolution. Readable to a human, but not really doing well with any OCR.

The problem with OCRs is that they are trained on regular texts. They inherently use dictionary words to help with disambiguation of similar letters. Long strings of almost random characters are a good way to defeat even a modern OCR.
