Erroneous encoding on form to Spring MVC

Question

I'm receiving form data in my Spring MVC controller, but when I try to input non-ASCII characters I receive rubbish, áéíóú gets converted into Ã¡Ã©ÃÃ³Ãº.

I'm using <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> in the jsp pages, Tomcat is configured to accept UTF-8 in the URI/Connection part and the form is set to acceptCharset="UTF-8". No idea where to look into next.

I'm testing on Firefox 38.0 in Ubuntu 14.04. The server is in Ubuntu 14.04 too.

You need to add an encoding filter to your web.xml to make it encode the chars correctly:

<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>

This is happening because the UTF-8 text is being read as latin1 encoding, which uses only one byte per char (for example, á (hex value C3 A1) is read as two latin1 chars Ã¡ (hex values C3 and A1)).

You can check the HTML output if it has the <meta> tag on the <head> section:

<meta charset="utf-8" /> (if you´re using HTML5 DOCTYPE).

Yes. For earlier HTML, use `` – Niloct May 21 '15 at 11:43
Nah, none works, might it be because its Content-Type is `application/x-www-form-urlencoded`? – Pedro Montoto García May 21 '15 at 11:55
Try a simple static HTML only page being served from Tomcat with an accent and the above tag. – Niloct May 21 '15 at 11:58
Every page gets served as `"text/html;charset=UTF-8"` even without the `meta` tags. – Pedro Montoto García May 21 '15 at 12:35
