title: 'Helvetica Neue' and Helvetica font
body: <p>I have seen a few of the the websites using font family:</p>
  
  <pre><code>font-family: 'Helvetica Neue',Helvetica,Arial,Sans-Serif
  </code></pre>
  
  <p>I remember reading in some older question here on stackoverflow that the Helvetica font is not free, and it is available on Mac only, is it so? I'm using windows XP and I can see that Font being rendered is '<code>Helvetica Neue</code>', and I don't remember installing any font by myself. so all I wanted to ask is if it is safe to use the above font family? (eg. will most of the windows computers render those fonts? )</p>
  
  <p>Thanks.</p>
