Reproducible: Always Steps to Reproduce: 1. Load a page in Arabic that has diacritics (Harakat). 2. Use the Find tool to search for a word that contains diacritics. Do not type in the diacritics (assuming they will be excluded from the text when it's checked). Actual Results: Example: "هذه الجُملة مثال." When you search for: "الجملة" nothing will be returned. Expected Results: Expected result: return "الجُملة". All words containing the search term should be found even if they use diacritics. I think this problem can be solved if the Find function searches in a version of the text that is stripped of diacritics unless a diacritic is found in the search term.
