Your characters are probably being corrupted by the compilation process and you're ending up with junk data in your class file.

if i run on linux with option -Dfile.encoding=ISO-8859-1 it works properly..

The "file.encoding" property is not required by the J2SE platform specification; it's an internal detail of Sun's implementations and should not be examined or modified by user code. It's also intended to be read-only; it's technically impossible to support the setting of this property to arbitrary values on the command line or at any other time during program execution.

In short, don't use -Dfile.encoding=...

 String x = "½"; 

Since U+00bd (½) will be represented by different values in different encodings:

windows-1252 BD UTF-8 C2 BD ISO-8859-1 BD 

...you need to tell your compiler what encoding your source file is encoded as:

javac -encoding ISO-8859-1 Foo.java 

Now we get to this one:

 System.out.println(x); 

As a PrintStream, this will encode data to the system encoding prior to emitting the byte data. Like this:

 System.out.write(x.getBytes(Charset.defaultCharset())); 

That may or may not work as you expect on some platforms - the byte encoding must match the encoding the console is expecting for the characters to show up correctly.
