title: What extended ASCII encoding is this and how can I get ruby to understand it?
body: <p>The characters <code>0x91</code>, <code>0x92</code>, <code>0x93</code>, and <code>0x94</code> are supposed to represent what in Unicode are <code>U+2018</code>, <code>U+2019</code>, <code>U+201c</code>, and <code>U+201d</code>, or the "opening single quote", "closing single quote", "opening double quote", and "closing double quote". I thought that it was <code>ISO-8859-1</code> but when I try to process a file using <code>IO.read('file', :encoding=&gt;'ISO-8859-1')</code> it still does not recognize these characters.</p>
  
  <p>If it isn't <code>ISO-8859-1</code> then what is it? And if it is, why doesn't ruby recognize these characters?</p>
  
  <p>UPDATE: Apparently this encoding is supposed to be Windows-1252. But ruby still does not recognize these characters when I do <code>IO.read('file', :encoding=&gt;'Windows-1252')</code>.</p>
  
  <p>UPDATE 2: Nevermind, <code>Windows-1252</code> works.</p>
