As @Tree suggested in comments, one can use the java.text.Collator for a case-insensitive and locale-sensitive String comparison. The following shows how both case and accents could be ignored for US English:

Collator collator = Collator.getInstance(Locale.US);
collator.setStrength(Collator.PRIMARY);
listOfEmployees.sort(Comparator.comparing(Employee::getName, collator.reversed()));

When collator strength is set to PRIMARY, then only PRIMARY differences are considered significant during comparison. Therefore, the following Strings are considered equivalent:

if (collator.compare("abc", "ABC") == 0) {
    System.out.println("Strings are equivalent");
}
