title: Emacs: is there a way to determine coding system of a file?
body: <p>Suppose I open a file and find there</p>
  
  <pre><code>Ïåñíÿ àëüïèíèñòîâ
  </code></pre>
  
  <p>and so on. Can I make emacs find the correct encoding? AkelPad for example has such feature - in most cases it'll open a file with a correct encoding.</p>
