title: Need method to convert Excel to Tab Delimited txt file in Unicode encoding
body: <p>I have some excel files containing some French characters, for example "Jean-Léon Gérôme"
  when I convert the excel file to tab delimited txt file, the default encoding is ANSI and the French characters became Gibberish, so I need a method that can convert the excel file to tab delimited file and at the same time in Unicode encoding.</p>
  
  <p>(I know excel can directly export to Unicode text, but that is not what I need, I need the file in <strong>tab delimited txt</strong> and in <strong>Unicode</strong> encoding)</p>
  
  <p>Please help. thanks a lot!</p>
