InputStreamReader, Charsets, and a surprise character

[aldend123]

I'm trying to write a parser that will read some xml code, altering only certain things, and printing the results to another file. I'm aware of xml parsers etc, but I needed something very specific. I'm using an InputStreamReader and a FileOutputStream with a PrintStream.

Demo/Test Sample

<xml>
&#177;
</xml>

Doing it with no charset specified (default Cp1252) results in :

<xml>
&#194;&#177;
</xml>

Why is another character added?

Simplified version of my code. This should open a file, read it, and output it to another file.

File file = new File("myfile.xml");
BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(file), "Cp1252"));
FileOutputStream out = new FileOutputStream("results.xml");
PrintStream p = new PrintStream(out, true, "Cp1252");
String textLine = new String();
		
while ((textLine = reader.readLine()) != null){
      p.println(textLine);		
}
		
reader.close();
p.close();

Thanks for the time
