title: Powershell - Encoding UTF-8 does not work at Export-Csv
body: <p>I'm trying to output a bunch of data and have some of the german Umlauts: ä, ö, ü,..
  I was adding -Encoding UTF8 at the end of Export-Csv, but it does not really work.
  My code:</p>
  
  <pre><code>For ($i = 0; $i -lt $accFileCont.Length; $i++) {
          $accFileCont[$i] | Export-Csv $outAccFile -NoTypeInformation -Encoding UTF8
      }
  </code></pre>
  
  <p>I'm expecting ä, ö, ü... instead of "Ã¤",...
  What is wrong here? It does not output the Umlauts.
  Thanks in advance :)</p>
