String2 = débárquér

On comparing above 2 str

Answer 1

To do this you can use Java's Normalizer class. Just normalize the Strings, then strip out the diacritical marks, like so:

String stripAccents(String string) {
    string = Normalizer.normalize(string, Normalizer.Form.NFD);
    string = string.replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
}

You can then use this to compare the two strings minus the accents:

stripAccents(string1).equals(stripAccents(string2))
