PrimeFaces 3.0.M3 UTF-8 encoding issues

Once PrimeFaces 3.0.M3 is added as dependency to the project, utf-8 encoding problems occur on form submits. To avoid these problems you will have to add a custom filter:

public class CharacterEncodingFilter implements Filter, Serializable 
{
    private static final long serialVersionUID = -4246457499875267088L;

    @Override
    public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws IOException, ServletException {
        req.setCharacterEncoding("UTF-8");
        resp.setCharacterEncoding("UTF-8");
        chain.doFilter(req, resp);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void destroy() {
    }
}

Add this part to your web.xml:

<filter>
    <filter-name>Character Encoding Filter</filter-name>
    <filter-class>com.your.package.to.CharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>Character Encoding Filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

After these changes are made, the utf-8 encoding problems won't occur anymore.
