How to fix encoding problems in a web application page?

I'm developing a JAVA application with the Spring framework v3.1.0, but when trying to access a page it has an encoding error:

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

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

But it did not 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 the encoding type in the header, and it also did not work:

<%@ 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 as well.

Does anyone have a solution to this problem? This is my first application in this technology, I'm picking up on these things.

Thank you in advance.
