Class Example

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      ' Many ways to instantiate a UTF8 encoding.
      Dim UTF8a As New UTF8Encoding()
      Dim UTF8b As Encoding = Encoding.UTF8
      Dim UTF8c = New UTF8Encoding(True, True)
      Dim UTF8d = New UTF8Encoding(False, False)

      ' But not all are the same.
      outputBlock.Text &= UTF8a.GetHashCode() & vbCrLf
      outputBlock.Text &= UTF8b.GetHashCode() & vbCrLf
      outputBlock.Text &= UTF8c.GetHashCode() & vbCrLf
      outputBlock.Text &= UTF8d.GetHashCode() & vbCrLf
   End Sub 'Main
End Class 'UTF8EncodingExample
