title: Does every browser support all unicode?
body: <p>I want to reduce the number of HTTP-requests by using Unicode instead of small image icons.</p>
  
  <p>The icons I'd like to use include ✔ ,► ,etc.</p>
  
  <p>For a complete list of all required characters, see <a href="http://en.wikipedia.org/wiki/List_of_Unicode_characters" rel="noreferrer">here</a></p>
  
  <ul>
  <li>Do all browsers support these characters by default?</li>
  <li>If not supported by default, can I add support for these characters?</li>
  <li>Which CSS and HTML are required to add these characters to a web page in a cross-browser way?</li>
  </ul>
  
  <p>Also, I am making a Unicode website that makes use of the following language:</p>
  
  <pre><code>यो भाषामा म वेबसाईट बनाउँदै छु 
  </code></pre>
  
  <ul>
  <li>Is it possible to get this language to be seen on every browser and every operating system?</li>
  <li>If it is possible to provide this support, which CSS and HTML code are required for this?</li>
  <li>Do I need to include a webfont for this?</li>
  <li>Which webfonts can I use and how do I add them in a cross-browser way?</li>
  </ul>
