Unicode sorting

[JackPotte]

Would it be possible to sort some non-English words please?

I can't send any pull request but this should work into LineOperations.java:

import java.text.Collator;
import java.util.Locale;
// line 149
                        Comparator<String> comparator = null;
                        Collator collator = null;
                        if (descending) {
                            if (matchCase) {
                                comparator = REVERSE_STRING_COMPARATOR;
                            } else {
                                comparator = REVERSE_STRING_COMPARATOR_CASE_INSENSITIVE;
                            }
                        } else {
                            if (matchCase) {
                                Locale locale = new Locale("fr_FR");
                                collator = Collator.getInstance(locale);
                            } else {
                                comparator = String.CASE_INSENSITIVE_ORDER;
                            }
                        }

                        if (isRemoveDuplicateLines()) {
                            SortedSet<String> uniqifySet = new TreeSet<String>(matchCase ? null : String.CASE_INSENSITIVE_ORDER);
                            uniqifySet.addAll(Arrays.asList(linesText));
                            linesText = uniqifySet.toArray(new String[0]);
                        }

                        if (comparator == null) {
                            Arrays.sort(linesText, collator);
                        } else {
                            Arrays.sort(linesText, comparator);
                        }
