title: Vim's encoding options
body: <p>Although Vim's help is a <em>treasure cave of information</em>, in some cases I find it mindboggling. Its explanation of different encoding-related options is one such case.</p>
  
  <p>Can someone please explain to me, in simple terms, what do <em>encoding, fileencoding and fileencodings</em> settings do, and how can I<br>
  a) view the encoding of the current file?<br>
  b) change the encoding of the current file?<br>
  c) do something else which is used often, but slips my mind right now?</p>
