DWe are using "Adobe World-Ready Paragraph Composer" instead of "Adobe Paragraph composer" for RTL characters. We are facing spacing issues due to this option in Adobe InDesing CC 2015. However, it is working fine in Adobe InDesign CS5.5. Please refer the paginated screenshot with highlighted instanced below. Please advise how to resolve this issue.
This bug is often caused because somewhere on the same page there are "special characters" -- perhaps right-to-left markers, or notes, or any other special characters.
Can you show the entire page with "hidden characters" showing? That might help to identify the problem.
I'm just surprised that you're not getting this same problem in CS5.5 as well -- it's not a new bug.
