The visual display is the same and you can normalization both to one form. But if a page contains both forms, the page search of Firefox does not find both. Reproducible: Always Steps to Reproduce: 1. Open a page with non-normalized Unicode. Here is an example: <html><head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> </head> <body> combined ü <hr> u with combining dots: ü </body></html> 2. Search for a combined character STRG+F, type "ü" Actual Results: Only the combined character "ü" is found Expected Results: Both instances should be found, no matter whether precombined or with combining character in the source document. You should normalize the page content by Unicode Normalization Form Canonical Composition (NFC).
Confirmed on Mozilla/5.0 (Windows NT 6.1; rv:6.0a1) Gecko/20110413 Firefox/6.0a1 Able to search only Combined character.
