Example PDF? Because I tried it too and it worked. Does your PDF use tags?

Any PDF from a generic google search? Here is one from Adobe https://www.adobe.com/support/products/enterprise/knowledgecenter/media/c4611_sample_explain.pdf https://www.adobe.com/support/products/enterprise/knowledgec... Or even better: their annual investor docs a team of professionals has spent time carefully preparing... like this https://www.adobe.com/pdf-page.html?pdfTarget=aHR0cHM6Ly93d3cuYWRvYmUuY29tL2NvbnRlbnQvZGFtL2NjL2VuL2ludmVzdG9yLXJlbGF0aW9ucy9wZGZzL0FEQkUtMjAyNC1TdG9ja2hvbGRlci1MZXR0ZXIucGRm https://www.adobe.com/pdf-page.html?pdfTarget=aHR0cHM6Ly93d3... (but don't look at the annual report, that marvel of a public disclosure document not only doesn't copy&paste paragraphs, but has another nice niche use of PDF - you get garbage chars instead of text, rather ironic) https://www.adobe.com/pdf-page.html?pdfTarget=aHR0cHM6Ly93d3cuYWRvYmUuY29tL2NvbnRlbnQvZGFtL2NjL2VuL2ludmVzdG9yLXJlbGF0aW9ucy9wZGZzL0FEQkUtMjAyMy1Bbm51YWwtUmVwb3J0LnBkZg== https://www.adobe.com/pdf-page.html?pdfTarget=aHR0cHM6Ly93d3...

  I tried a few documents and got the same result (ie. each line being treated as separate paragraphs), but was able to find that the fed FOMC meeting doc[1] actually worked properly, but only on adobe acrobat. It was still screwed up on pdf.js. So I guess the format itself technically supports it, but implementations rarely do it properly.

  The first two work just fine in Adobe Acrobat Reader on iOS. The third is garbage, probably because the producer didn't include a ToUnicode map or equivalent. The format supports a lot that is not commonly implemented by PDF readers (or PDF producers).

    How does this help me on Windows? And a good format wouldn't require any ToUnicode maps for simple text in the first place And poorly supporting a lot without common implementations isn't a defence against the charge of high complexity and bad design, but a reinforcement thereof (also, no, the first document doesn't work on iOS, I select title and two paragraphs, copy, paste, and I get a single line instead of 3, so a different manifestation of the same common fail of PDFs)

      “Here’s a nickel kid, get yourself a better OS”? Still, the fact that some PDF processors can make this work shows that the format isn’t broken “by design”.
