java - Reading UTF-8 - BOM marker

Question

I'm reading a file through a FileReader - the file is UTF-8 decoded (with BOM) now my problem is: I read the file and output a string, but sadly the BOM marker is outputted too. Why this occurs?

fr = new FileReader(file);
br = new BufferedReader(fr);
    String tmp = null;
    while ((tmp = br.readLine()) != null) {
    String text;    
    text = new String(tmp.getBytes(), "UTF-8");
    content += text + System.getProperty("line.separator");
}

output after first line

In Java, you have to consume manually the UTF8 BOM if present. This behaviour is documented in the Java bug database, here and here. There will be no fix for now because it will break existing tools like JavaDoc or XML parsers. The Apache IO Commons provides a BOMInputStream to handle this situation.
