title: OpenOffice when exporting CSV underscores are replaced with "+AF8-"
body: <p>I'm having issues with a Open Office. I'm trying to export some files as CSV text and it appears that underscores and perhaps some other characters are being replaced. For instance, I created this file in a text editor and saved it as test.csv:</p>
  
  <pre><code>"this_value","is_replaced"
  </code></pre>
  
  <p>I then opened the file into Open Office as a spreadsheet. It looked fine. Then I saved it as a new CSV file named test-export.csv. When I open the new file in a text editor, the underscores are replaced with "+AF8-", and the comma is replaced with a tab.</p>
  
  <pre><code>this+AF8-value  is+AF8-replaced
  </code></pre>
  
  <p>This change makes the file useless for my purposes. Any idea what is causing this?</p>
