Hello,
I have been using Indesign v18.5 and created a lot of documents for a book in Hebrew and Arabic.
My paragraph styles have the property "Character Direction: Default" which, of course, organized my text as RTL for Hebrew and Arabic, and LTR for English text.
After converting the documents to the newest version (v19.0), some (and only some) of the punctuation marks (such as ".", "!", "?") and even some of the spaces, were placed in a wrong manner: to the right side of the text, instead of being placed to the left of the text as they are supposed to be.

I noticed that when I apply "Character Direction: Right-to-left" they get back to the right position, but I can't do that for all of the text, because I also have English text in the book. I also noticed that when I delete these punctuation marks and write them again the issue gets fixed for most of the cases. I can't do that manually because there are a lot of cases like that and I have over 30 documents.

I can't attach the Indesign document with the issue, so I am adding a screenshot of it. Let me know how I can provide more information or an indesign document with the issue.

Thanks,

Nadav
