The comparator for matching text does not obey the rules of Unicode equivalence for matching accented characters to their decomposed forms. This is reproduceable across products (tested FF and TB) and platforms (tested Vista and Ubuntu).

Reproducible: Always

Steps to Reproduce:
1. Visit http://en.wikipedia.org/wiki/Tom%C3%A1%C5%A1_Rosick%C3%BD
2. Press CTRL+F
3. Type "Tomas" or "Rosicky"

Actual Results:  
Only where the text has been Anglicised does it get highlighted, the accented versions are not found.

Expected Results:  
Highlighted the equivalent strings "Tomáš" and "Rosický".

Software that uses this type of matching includes: Webkit (Chrome/Safari), MySQL and Google Search.
