Tomcat's URIEncoding="UTF-8" is ignored by UrlRewriteFilter

What steps will reproduce the problem?

1. Add the attribute URIEncoding="UTF-8" to Tomcat's server.xml "<Connector>" 
tag.

2. Create a simple JSP page (e.g. "search.jsp") that prints out the "item" 
parameter.

3. Call this JSP directly with an UTF-8 encoded URL, like :

http://localhost:8080/MyProject/search.jsp?item=m%C3%A9tro

The parameter is "métro" encoded in UTF-8, and it is correctly decoded by 
Tomcat with respect to the URIEncoding="UTF-8" option.

4. Now, set up URL Rewrite Filter with the following rule :

<urlrewrite use-query-string="true" decode-using="UTF-8">
    <rule match-type="regex">
        <from>^/recherche\?item=([%\+\-0-9a-zA-Z;]+)$</from>
        <to>/search.jsp?item=$1</to>
    </rule>
</urlrewrite>

5. Call your JSP through the address :
http://localhost:8080/MyProject/recherche?item=m%C3%A9tro

What is the expected output? What do you see instead?

It should return "métro", just like the direct call to the JSP. Instead, it 
displays the ISO-8859-1 string : "mÃ©tro".

What version of the product are you using? On what operating system?

Tomcat 7 and URL Rewrite Filter 3.2
