Problem replacing chars in String.replaceAll(), Chars such as (1/2) ½ and (1/4) ¼

[fortwnty420]

I'm having a problem using the replace function with the String.replaceAll();

In the following code, it doesn't seem to be able to see or replace certain chars for trademark, registered, and a couple of other chars.

// I get the line of data from a file and store it in line.

String new_line = "";
new_line=line;
new_line = new_line.replaceAll("\\?\"", "\"");
new_line = new_line.replaceAll("\"\"", "-in.");
new_line = new_line.replaceAll("\'", "\\'");
new_line = new_line.replaceAll("\"", "");

// Everything works up till this point..
// contains doesn't see them and replace doesn't replace it even if it did see it.

if (new_line.contains("¾")){
new_line = new_line.replace("¾", ".75");
System.out.printf("Contains a ¾ (3/4)");
// System.exit(0);
}


if (new_line.contains("¼")){
new_line = new_line.replace("¼", ".25");
System.out.printf("Contains a ¼ (1/4)");
System.exit(0);
}

if (new_line.contains("½")){
new_line = new_line.replace("½", ".50");
System.out.printf("Contains a ½ (1/2)");
// System.exit(0);
}

// I doesn't work for these either.

new_line = new_line.replaceAll("©", "(C)");
new_line = new_line.replaceAll("®", "(R)");
new_line = new_line.replaceAll("™", "(TM)");
new_line = new_line.replaceAll("É", "E");
new_line = new_line.replaceAll("é", "e");

// Not really a show stopper, but, I"m getting tired of doing search and replaces..

// Any help greatly appreciated..

This code:

      String new_line = "new_line.replace(¾, .75)";
      if (new_line.contains("¾")){
          new_line = new_line.replace("¾", ".75");
          System.out.println("R nL=" + new_line);
      }
      System.out.println("nL=" + new_line);

      new_line = "replaceAll(©, (C))";
      new_line = new_line.replaceAll("©", "(C)");
      System.out.println("nL=" + new_line);

generates this output:

R nL=new_line.replace(.75, .75)
nL=new_line.replace(.75, .75)
nL=replaceAll((C), (C))

Works for me:

public class ReplaceEg {
	public static void main(String[] args) {
		String test = "©©-- Asd © ©";
		
		test = test.replaceAll("©", "(C)");
		System.out.println("output=" + test);
	}
}


output=(C)(C)-- Asd (C) (C)

It might be a good idea to output new_line after each replaceAll() so you can see the effect of that method. If you are still stuck provide a SSCCE that illustrates the problem.
