replacing characters

[Fernando Dominguez]

Hello, I am trying to replace a strange character from an string.

String cadena 2= "";
String  cadena = "asdf�";
cadena2 = cadena.replaceAll("�");

replaceAll does not work with � , it returns the same string "asdf�"

I notice that � this character does not exits in the ascii code, � � exits in the extended ascci code but not � alone.

I have looked into the character api but I dont found anything usefull.

Any idea to replace the � from an string?
Is there any method that returns the ascii code from a character?

Thanks.

public class TestString{
public static void replaceStr(){
String trial1="";
String trial2="arun'";
trial1=trial2.replaceAll("\'","");
System.out.println(trial2);
System.out.println(trial1);

}
public static void main(String args[]){
replaceStr();
}
}

Thanks for your interest.

replaceAll works well with (') quote,

but does not work with (�) spanish accent.

Thanks

Please check if this helps

String cadena2 = "";
String cadena = "asdf�";
char c = 0xB4;
cadena2 = cadena.replaceAll(""+c,"");
System.out.println("cadena2 : "+cadena2);

I am not sure if this is the character code you have stated.

One URL that can be of help is

Sorry, i'm confusing about what you said, because java replaceAll() method working fine for me to replace these characters.

public class TestString{
 
public static void main(String args[]){
 
String test1="Test 1 = replace'";
 
      System.out.println("Before : " + test1);
 
  test1=test1.replaceAll("'","");
 
      System.out.println("After : " + test1);
 

      //spanish word?
String test2="Test 2 = replace�";
 
      System.out.println("Before : " + test2);
 
  test2=test2.replaceAll("�","");
 
      System.out.println("After : " + test2);
 

  }
} 

Result

D:\>java TestString
Before : Test 1 = replace'
After : Test 1 = replace
Before : Test 2 = replace┤
After : Test 2 = replace

Any idea why it work for me? I'm using JDK 1.6.0.07

Are you working on a windows machine?

I am working on an UNIX machine
I tried the "original" replaceAll on a windows machine and It worked.

So problem could be the way that both OS/editors uses the caracters.

It is in Unicode; look in Latin-1; its code number is 0x00b4.

Yes, i tested on windows platform. Thanks for info. I will be careful on my UNIX production server when dealing with special characters.

[Campbell Ritchie]

That is peculiar; Java supports the whole of Unicode, and it is usually only a problem on Windows because the Windows command prompt doesn't support special characters. I don't use Unix, but the special character support on Linux which is similar to Unix is usually better than on Windows.

Can you check what is the value you are getting for the following in Windows and Unix?

System.out.println(""+Integer.toHexString((int)'�'));

In windows I get "b4"
0xb4 is the character code.

[Fernando Dominguez]

Sorry for being so late.

I get b4 on my eclipse console on a debian linux.

Bye

[Rob Spoor]

b4? Are we playing Bingo?

Please Use Real Words.

Hi Rob,

I think Fernando meant character "0xb4" when he mentioned "b4". Not "before".

Thanks,
Vipin

Ah, you're right. I missed your post when I read his
