I have one form with only one single field. When I submit the form, the value of my field becomes strange. The word Extremação becomes ExtremaÃ§Ã£o.

So, I already set UTF-8 encoding in every place on my app:

<?xml version="1.0" encoding="UTF-8"?>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<f:view contentType="text/html" encoding="UTF-8">
<h:form id="formParamSupremo"  prependId="false" acceptcharset="UTF-8">

I created one encoding filter too:

request.setCharacterEncoding("UTF-8");
response.setContentType("text/html; charset=UTF-8");

And my http header is like this:
