Look at icu4j or the JDK 1.6 Normalizer:

public String removeAccents(String text) {
    return Normalizer.normalize(text, Normalizer.Form.NFD)
                     .replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
}

You probably meant "Normalizer.normalize(text, Normalizer.Form.NFD)" instead of "Normalizer.decompose(text, false, 0)" – Steve Emmerson Dec 26 '09 at 18:58
I think I accidentally put in the old sun. class scheme instead. Thanks for catching it. – bmargulies Dec 26 '09 at 19:42
Normalizer.Form.NFKD may be better than Normalizer.Form.NFD for his purposes, depending on how he wants to treat ligatures. eg: NFKD will transform `"ﬁ"` into `"fi"`. – Laurence Gonsalves Dec 26 '09 at 21:34
http://stackoverflow.com/a/3322174/535203 says `replaceAll("[^\\p{ASCII}]", "");` – Anthony O. Jan 08 '13 at 16:37

As far as I know, there's no way to do this automatically -- you'd have to substitute manually using String.replaceAll.

String str = "Paraná";
str = str.replaceAll("á", "a");
str = str.replaceAll("Æ", "a");

Try something similar to the following code snippet:

import org.apache.commons.lang3.StringUtils;

public class Test {
    public static void main(String[] args) {

        String original = new String("Ramesh Öhrman");
        try {
            
            System.out.println(StringUtils.stripAccents(original));
            
        } catch (Exception e) {
        }
        
    }
}

Output: Ramesh Ohrman
