title: Get Barcode 128 encoded text. I want to use a Barcode font to show it, not generate images
body: <p>I would like to get a class or function, if possible written in VB.NET, to add it to my projects.
  This class or function should be able to receive a text and return it as Barcode 128 encoded text.</p>
  <p>I found lot of solutions for generating the barcode images directly, but what I need it's only the part which converts a text to a Standard Code 128 encoded text, then I will show it using a Barcode font.</p>
  <p>I also found some codes to do it, but the returned encoded text is not the expected one, because I cannot read it with the Barcode Reader, or sometimes appears a char which cannot be represented by the barcode font.</p>
  <p>The encoder should be able to convert this:</p>
  <blockquote>
  <p>15868/039</p>
  </blockquote>
  <p>Into this:</p>
  <blockquote>
  <p>Í/vÈ8/039[Î</p>
  </blockquote>
  <p>As this online converter can do it <a href="https://www.bcgen.com/fontencoder/" rel="nofollow noreferrer">https://www.bcgen.com/fontencoder/</a> when you click on the button [Code 128]</p>
