title: How can I omit Helvetica with TCPDF?
body: <p>I'm making a PDF with TCPDF, and I'm trying to make the file as small as possible.  The font I'm using is Open Sans.  I'm not (intentionally, at least) using Helvetica anywhere in the PDF.  When I view the included fonts with Adobe Reader in my outputted PDF file, both Open Sans and Helvetica are listed.  I have noticed that if I <code>AddFont()</code> other fonts, the outputted PDF gets bigger.</p>
  
  <p>To save space, how can I tell TCPDF to not include Helvetica in the file?</p>
