title: ö character encoding issue in CSV file creation
body: <p>I am trying to create a CSV file from my Java code.</p>
  
  <pre><code>    File file = File.createTempFile("DummyReport", ".csv");
      SomeListofObjects items = getSomeList();
      FileUtils.write(file, "ID;CREATION;" + System.lineSeparator());
      FileUtils.writeLines(file, activities.getItems(), true);        
      return file;
  </code></pre>
  
  <p>I am facing some issue with special chars.</p>
  
  <p>When I debug the code, I found that I have a character as "ö". But in the csv file generated, it is coming weirdly "Ã¶".</p>
  
  <p>Can we set this in FileUtile or File? Can some one help me to solve this?</p>
