I added this test method locally to TestASCIIFoldingFilter.java in the 
Lucene/Solr 3.1.0 source tree, and it passed, so the filter is not the problem 
(and the Solr factory certainly isn't either - it's just a wrapper) - I second 
Ludovic's question - you must have other filters configured:

  public void testPluralNotTrimmed() throws Exception {
    TokenStream stream = new WhitespaceTokenizer(TEST_VERSION_CURRENT, new 
StringReader
      ("después Imágenes"));
    ASCIIFoldingFilter filter = new ASCIIFoldingFilter(stream);
    CharTermAttribute termAtt = filter.getAttribute(CharTermAttribute.class);

    assertTermEquals("despues", filter, termAtt);
    assertTermEquals("Imagenes", filter, termAtt);
  }
