How to fix encoding problems on a web application page?

Question

I am developing a JAVA application with the Spring framework v3.1.0, however, when trying to access a page shows error of encoding:

Evoluã§

How to solve this problem? I found several ways, but none worked:

<servlet-container name="default" use-listener-encoding="true" default-encoding="UTF-8">
     <jsp-config/>
     <websockets/>
</servlet-container>

But it didn’t work, I also tried to put the filter in the web.xml file.:

<filter>
    <filter-name>encoding-filter</filter-name>
    <filter-class>
         org.springframework.web.filter.CharacterEncodingFilter
    </filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>encoding-filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

I also put in the header the type of encoding, and it didn’t work either:

<%@ page language="java" contentType="text/html; charset=UTF-8;" pageEncoding="UTF-8" %>

Of course, I also tried to pass this information via HTML:

<meta charset="UTF-8" />

The JSP file is also in UTF-8 and the browser is also.

Does anyone have a solution to this problem? This is my first application in this technology, I’m getting a little bit of this stuff.

Thanks in advance.
