Strange issue and probably hard to reproduce? Could you reproduce the issue yourself? What browser version? What OS? What Kirby version? Does this happen in another browser as well? What sort of PDF created by what sort of program? Maybe the PDF contains hidden characters.
Now, I cant reproduce the issue, neither in mac os preview or in acrobat or in PDFs from indesign. But I have had the same issue sometimes. Since then I never copy text from PDF. It’s not a good idea anyhow. I tell my customer not to deliver PDF’s. But I will ask my last customer who have that problem.
The problem only occurs in Firefox and Firefox related Browser like Cliqz.
This is nothing Kirby can fix, I think. I’d suggest your clients use another browser if they insist on copying from PDF and can live with the other issues caused by copying from PDF. It’s not a good idea to copy from Word, either, by the way. It often introduces hidden chars that can completely mess up the layout.
I can totally understand that people don’t want to manually type everything in if the content is already there. But then they have to take precautions and live with the fact that this can cause issues. In your client’s case, they can probably use a different browser to work around this issue.
I’ll close this topic because there’s nothing we can do about it.
You are definitely right. For a propper understanding:
It’s not copying text in the backend via Firefox Browsers. It’s only Firefox who diplays the blancs in the frontend view, Chrome, Safarie, Opera etc. dont show blancs. I guess I did not express myself well.
