As the title suggests, I am using XeLaTeX to layout very long paragraphs (up to 50 pages in length for a single paragraph), and would like to encourage it to break pages at the end of sentences within a paragraph as opposed to the middle of sentences. Currently, it seems equally happy to break at either. Is there a way to do this, or do I need to consider switching to LuaTeX?
One added complication, I am typesetting in Arabic, and the punctuation used to demarcate one sentence from the next is non-standard (these are Ayat in a Quranic Mashaf).
Thank you for any suggestions.
