Scrivener made PDF, opened in Adobe Reader 9. Windows Vista.
We know it doesn’t keep formatting. Additionally, if you have the PDF read out loud, at the end of each carriage return it speaks the letter J. I’m not talking about when you start a new paragraph. I mean at the end of every sentence as the text wraps to the next line, regardless of where it is in a sentence or a paragraph.
Strangely, if the ‘carriage return’ just happens to end with a period, the read out loud voice will say " dot J" as it goes to the next line of text.
