Java change áéőűú to aeouu [duplicate]

Possible Duplicates:
Remove diacritical marks (ń ǹ ň ñ ṅ ņ ṇ ṋ ṉ ̈ ɲ ƞ ᶇ ɳ ȵ) from Unicode chars
Is there a way to get rid of accents and convert a whole string to regular letters?

How can i do this? Thanks for the help


Solution 1:

I think your question is the same as these:

  • Java - getting rid of accents and converting them to regular letters
  • Converting Java String to ascii

and hence the answer is also the same:

String convertedString = 
       Normalizer
           .normalize(input, Normalizer.Form.NFD)
           .replaceAll("[^\\p{ASCII}]", "");

See

  • JavaDoc: Normalizer.normalize(String, Normalizer.Form)
  • JavaDoc: Normalizer.Form.NFD
  • Sun Java Tutorial: Normalizer's API)

Example Code:

final String input = "Tĥïŝ ĩš â fůňķŷ Šťŕĭńġ";
System.out.println(
    Normalizer
        .normalize(input, Normalizer.Form.NFD)
        .replaceAll("[^\\p{ASCII}]", "")
);

Output:

This is a funky String

Solution 2:

You can use java.text.Normalizer to separate base letters and diacritics, then remove the latter via a regexp:

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

Solution 3:

First - you shouldn't. These symbols carry special phonetic properties which should not be ignored.

The way to convert them is to create a Map that holds each pair:

Map<Character, Character> map = new HashMap<Character, Character>();
map.put('á', 'a');
map.put('é', 'e');
//etc..

and then loop the chars in the string, creating a new string by calling map.get(currentChar)
