       <param-name>requestEncoding</param-name>
       <param-value>UTF-8</param-value>
     </init-param>
     <init-param>
       <param-name>excludeUrls</param-name>
       <param-value>action1.do;action2.do</param-value>
     </init-param>
 </filter>

 <filter-mapping>
   <filter-name>Charset Filter</filter-name>
   <url-pattern>/*</url-pattern>
 </filter-mapping>
 

If requestEncoding not declared then the default value is UTF-8.
Parameter excludeUrls is optional. Using this parameter you can exclude some actions/urls to be process by this filter. The values are separated by ";". You don't have to add all the url: only the part after last "/" must be given.
