title: Vi character encoding issue
body: <p>I am trying to see the contents of a Finnish text on vi. However, it replaces some letters with numbers. For example, <code>&lt;8a&gt;</code> stands for <code>ä</code>, etc. </p>
  
  <p>I changed the character encoding to ISO8859-1, however still when viewing the file, it cannot show the umlaut letters. I also tried <code>:set encoding=latin1</code> on vi, however it changes to different letters but not umlaut letters. Finally, I tried to replace those numbers with the original letters, but I am getting 'pattern not found' error. I am not sure whether I am doing the substitution correctly though: <code>%s/&lt;8a&gt;/ä</code> </p>
  
  <p>Are there any more solution ideas?</p>
