This program write on 2 files.
In the right file the string is "IL RITROVO AL 1° PIANO"
In the wrong file the string is "IL RITROVO AL 1NUL PIANO".
In the second case, the "°" charater has wrong econding; how can I detect this case before I write it?

};
write(wrongFile, wrongBytes) ;
byte[] rightBytes = "IL RITROVO AL 1° PIANO".getBytes();
write(rightFile, rightBytes) ;
}
static void write(File file, byte[] bytes) throws IOException{
OutputStreamWriter stream = null; //10227
stream = new OutputStreamWriter( new FileOutputStream( file ) , "ISO-8859-15");
stream.write( new String( bytes ) );
stream.flush();
stream.close();
}
}
Thanks, but this is what I wanted, but I'm not be able to do with CharsetDecoder....
