title: What encoding/character set does Java use per default for BufferedReader?
body: <p>What encoding/character set does Java use per default when we create a new <code>BufferedReader</code> object without providing an encoding explicitly?</p>
  
  <p>For example:</p>
  
  <pre><code>try (final BufferedReader reader = new BufferedReader(new FileReader("my_file.txt"))) {
    reader.readLine(); // What encoding is used to read the file?
  }
  </code></pre>
