title: What is the difference between embedded web fonts and regular TrueType desktop fonts?
body: <p>I have a good free desktop font and it is free also for font embedding on the web.
  The font uses Arabic Unicode and it is TrueType desktop font.</p>
  
  <p>I want to use this font on my website. The problem that most web font converters or generators like font squirrel and typeface.js render the letters separately, not linked together.</p>
  
  <p>I used this Unicode ranges to create the web fonts:</p>
  
  <pre><code>FE70-FEFF,0600-06FF,FB50-FDFF,0750-077F,0621-0652
  </code></pre>
  
  <p>This should convert all Arabic Unicode characters and should make the letters linked together or attached together like what happen on desktop font but that does not happen.</p>
  
  <p>Can I just use the desktop font file itself without converting it?
  What is the difference between a regular desktop font and web embedded font?
  BTW, the font desktop file is only 27kb and I tested it in Firefox. It is working great if installed on the system (of course it is on my computer).</p>
