title: VB.Net: Replace special characters like "_x000D_" with their equivalent values within a string
body: <p>I am uploading a few free-text values from an Excel spreadsheet into my VB.NET project and saving values in the SQL server database.
  But a few special characters like <code>_x000D_</code> were saved into the database (they weren't visible in Excel spreadsheet).</p>
  
  <p>How can this be converted to its original values before saving them into the database? </p>
  
  <p>I thought to replace them using the <code>Replace("_x000D_", vbcrlf)</code> function, but I am not sure if there would be any other special characters (and their equivalent values in VB.Net)?</p>
