PrimeFaces: UTF-8 bug related to file upload

Question

My web applications is currently using:

JBoss AS7
JSF2
PrimeFaces

Due to this bug UTF-8 form submit in JSF is corrupting data I setup a @WebFilter doing

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws ServletException, IOException {
        request.setCharacterEncoding("UTF-8");
        chain.doFilter(request, response);
    }

as suggested by BalusC (thank you).

In a simple it always works right. I come to another problem when I need to use the same form for file upload, too (e.g. http://www.primefaces.org/showcase-labs/ui/fileUploadDnd.jsf)

Here's the main difference

 <h:form enctype="multipart/form-data">

WITHOUT the enctype attribute, special unicode characters remains readable.

WITH the enctype attribute, I find "ciaÃ²" instead of "ciaò".

My filter @WebFilter("/*") EncodingFilter is always called however.

Could a possible solution be setting JBoss default encoding to utf-8? How can I do that?

*** * EDIT ****

I also tried putting -Dfile.encoding=UTF-8 in my JAVA_OPTS but nothing.... it won't work :(( Please help me!

nice but.... 1) what do you mean by "platform"? the os? jboss-as? how can I change the "default encoding" 2) I don't want to convert each of my form strings... what's the actual better solution? How can I modify primefaces? isn't there another way to go? — Fabio B.
there is an explanation in that answer of what you should fix in primefaces jar in order to fix that issue (just saw that answer i don't really know if its exact issue as yours..) — Daniel

This is caused by another bug in PrimeFaces. See also this answer for explanation and solution.

Yes. How to do that depends on JBoss version. In the ones who have a server.xml (until with version 6.x), it's a matter of adding URIEncoding="UTF-8" to the <Connector> element. In the ones who have a standalone.xml (7.x and newer), it's a matter of adding <property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/> to the <system-properties> element.
