title: Replace first character in string
body: <p>I have a CSV file where I want to replace the first character that is 0 with +46 but I can't make this work as I want to.</p>
  
  <p>I have the following code that works, but it works on all zeroes and not only the first one:</p>
  
  <pre><code>$csv = Import-Csv test.csv
  $csv | ForEach-Object {
      $_.mobile = $_.mobile.Replace("0", "+46")
  }
  $csv | Export-Csv -Encoding "UTF8" new-test.csv -NoTypeInformation
  </code></pre>
  
  <p>Any idea how to make this work only on the first character in the string?</p>
