Problem with Spring Security, Spring Web Stream, File Upload and UTF-8

I have a problem very similar to that described here: Uploading files using Spring WebFlow 2.4.0, the parameter is not bound , but this one did not mention UTF-8 problems. I am using Spring Framework 4.1.6, Spring Security 4.0.2 and Spring Webflow 2.4.2.

It revolves around StandardServletMultipartResolvervs. CommonsMultipartResolveras far as I can judge, but I'm not sure. If I use CommonsMultipartResolver, I can upload files to any page except Webflow pages, and UTF-8 encoding also works on all pages. However, an exception is thrown on the Webflow pages trying to access the file. If I use StandardServletMultipartResolver, then all files are uploaded, including Webflow, but on any page with a UTF-8 symbol, for example, caractère, I get garbage.

The strangest thing I can see in FireBug is that the file is sent when I use resolons. Also, if I am debugging RequestContext, coming from Webflow, I can also see that the file looks like 4 levels deep in requests. Code for common resolver (see End of message for standard recognizer code):

public FileResult uploadFile(Recipe recipe, RequestContext requestContext) {
    ServletExternalContext context = (ServletExternalContext) requestContext.getExternalContext();
    MultipartHttpServletRequest multipartRequest = new DefaultMultipartHttpServletRequest((HttpServletRequest)context.getNativeRequest());
    MultipartFile file = multipartRequest.getFile("file");

@Bean
public CommonsMultipartResolver filterMultipartResolver() {
    CommonsMultipartResolver resolver = new CommonsMultipartResolver();
    resolver.setDefaultEncoding("UTF-8");
    return resolver;
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
    characterEncodingFilter.setEncoding("UTF-8");
    characterEncodingFilter.setForceEncoding(true);

    //.csrf().disable()
    .addFilterBefore(characterEncodingFilter, CsrfFilter.class)

    insertFilters(servletContext, new MultipartFilter());

    ServletExternalContext context = (ServletExternalContext) requestContext.getExternalContext();

    MultipartFile file = multipartRequest.getFile("file");
