title: how to change explicitly encoding in Jackson?
body: <p>I'am using <code>Jackson</code> to map a json file to java object and there is an element in the json file that contains the character <code>É</code>,I got the error below: </p>
  
  <pre><code>Caused by: com.fasterxml.jackson.core.JsonParseException: Invalid UTF-8 middle byte 0x41
   at [Source: (File); line: 129, column: 35]
      at com.fasterxml.jackson.core.JsonParser._constructError(JsonParser.java:1804) 
  </code></pre>
  
  <p>So, is there a way to change the default encoding of the <code>objectMapper</code> from <code>utf-8</code> to <code>utf-32</code>?<br>
  Thanks!</p>
