I did not know, that pdf with text layer is not touched by ocrmypdf. But it is really curious. I scanned all my documents with scansnap to searchable pdfs. When i open them on osx and copy text, everything is fine. When i open the same pdf an windows, then there are additional spaces after each letter. So why the hell is it so? Hard to find any information on the internet.
