I think documentation is pretty clear: http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/filter/CharacterEncodingFilter.html

"Servlet Filter that allows one to specify a character encoding for requests. This is useful because current browsers typically do not set a character encoding even if specified in the HTML page or form."
