how to replace Latin unicode character to [a-z] characters

Question

I'm trying to convert all Latin unicode Character into their [az] representations

ó --> o
í --> i

I can easily do one by one for example:

myString = myString.replaceAll("ó","o");

but since there are tons of variations, this approach is just impractical

Is there another way of doing it in Java? for example a regular Expression , or a utility library

USE CASE:

1- city names from another languages into english eg

Espírito Santo --> Espirito Santo,

Answer 1

This answer requires Java 1.6 or above, which added java.text.Normalizer .

    String normalized = Normalizer.normalize(input, Normalizer.Form.NFD);
    String accentRemoved = normalized.replaceAll("\\p{InCombiningDiacriticalMarks}+", "");

Example:

public class Main {
    public static void main(String[] args) {
        String input = "Árvíztűrő tükörfúrógép";
        System.out.println("Input: " + input);
        String normalized = Normalizer.normalize(input, Normalizer.Form.NFD);
        System.out.println("Normalized: " + normalized);
        String accentRemoved = normalized.replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
        System.out.println("Result: " + accentRemoved);
    }
}

Result:

Input: Árvíztűrő tükörfúrógép
Result: Arvizturo tukorfurogep
