@svenkapudija 's excellent answer can be generalized to most Latin script languages using java.text.Normalizer. In the filter code, replace:

                    String valueTextNoPalatals = toNoPalatals(valueText);
                    String prefixStringNoPalatals = toNoPalatals(prefixString);

with:

                String valueTextNoPalatals = Normalizer
                        .normalize(valueText, Normalizer.Form.NFD)
                        .replaceAll("[^\\p{ASCII}]", "")
                        .toLowerCase();

                String prefixStringNoPalatals = Normalizer
                        .normalize(prefixString, Normalizer.Form.NFD)
                        .replaceAll("[^\\p{ASCII}]", "")
                        .toLowerCase();
