Error in file name encoding on OS X

Question

This little java program fails when creating a new file with the Danish letter "�" (U+00C5) and then trying to find the same file. It cannot find it - the name has been messed up in the encoding/decoding.
The program only fails on OS X 10.4. The charset is MacRoman. If I look for the file in OS X it looks fine.
It runs fine on Windows XP.
Anyone who can explain this?
public class Test
    public static void main(String []args)
        try
            String arr[] = {
                    "\u0026\u0416\u4E2D\u10346"    //http://www.tbray.org/ongoing/When/200x/2003/04/26/UTF
                    ,"\u00C5" //AA
                    ,"\u00d8" //OE
                    ,"\u00E6" //AE
            for (int i = 0; i<arr.length; i++)
                String filename = arr;
String folder = "/Users/.../shared/1/";
java.io.File f = new java.io.File(folder + filename);
f.createNewFile();
f = new java.io.File(folder);
boolean found = false;
String[] files = f.list();
for (int j=0; j<files.length; j++)
if (files[j].equals(filename))
found = true;
System.out.println(arr[i] + " : " + found);
catch (Exception ex)
System.out.println(""+ex);

Answer 1

Here is a even more clear example that something is wrong. CompareTo returns != 0 for all files in a folder, even when compared to the file object, from which a file was just created.
Again this works fine with Windows XP.
public class Test
     public static void main(String []args)
          try
               String filename = "\u00C5"; //Danish �
               String folderPath = "/Users/.../shared/";
               //Create file.
               java.io.File file = new java.io.File(folderPath + filename);
               file.createNewFile();
               //Loop folder          
               java.io.File folder = new java.io.File(folderPath);
               java.io.File[] files = folder.listFiles();
               for (int j=0; j<files.length; j++)
                    java.io.File folderFile = files[j];
                    System.out.println(folderFile + " compareTo: " + file.compareTo(folderFile));
          catch (Exception ex)
               System.out.println(""+ex);
