I cannot get the GB2312 converter to use the replacement character.
I guess a bug.

var data = "\u0080"; // invalid
var file = Components.
  classes["@mozilla.org/file/directory_service;1"].
  getService(Components.interfaces.nsIProperties).
  get("ProfD", Components.interfaces.nsIFile);
file.append("test.txt");
var stream = Components.
  classes["@mozilla.org/network/file-output-stream;1"].
  createInstance(Components.interfaces.nsIFileOutputStream);
var converter = Components.
  classes["@mozilla.org/intl/converter-output-stream;1"].
  createInstance(Components.interfaces.nsIConverterOutputStream);
try {
  stream.init(file, 0x02|0x08|0x10, parseInt("666", 8), 0);
     converter.init(stream, "ISO-8859-1", 0, 0x0000);
  // converter.init(stream, "ISO-8859-1", 0, 0x0041);
  // converter.init(stream, "GB2312", 0, 0x0000);
  // converter.init(stream, "GB2312", 0, 0x0041);
  converter.writeString(data);
} finally {
  converter.close();
  stream.close();
}
