Answer 1

You can use java.text.Normalizer which comes close to normalizing Strings in Java. Though regex are also a powerful way to manipulate the Strings in whichever way possible.

Example of accent removal:

String accented = "árvíztűrő tükörfúrógép";
String normalized = Normalizer.normalize(accented,  Normalizer.Form.NFD);
normalized = normalized.replaceAll("[^\\p{ASCII}]", "");

System.out.println(normalized);

Output:

arvizturo tukorfurogep
