User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Ubuntu/10.04 Chromium/10.0.648.133 Chrome/10.0.648.133 Safari/534.16

Several Unicode characters can be represented in two ways: as one precomposed codepoint or as combination of a character with combining characters. 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: u&#x0308;
</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.
