title: change default character set of PHP functions like "htmlspecialchars"
body: <p>I am using PHP 5.2.6 and my app's character set is UTF-8.</p>
  
  <p>Now, how should I change PHP's default character set? 
  NOT the one which specifies output's mime time and character set.</p>
  
  <p>But which will change for all the PHP function like htmlspecialchars, htmlentities, etc.</p>
  
  <p>I know, there is a parameter in those functions which takes the character set of the input string. But I don't want to specify for all the functions I use. And if somewhere I forget, it will be mess.</p>
  
  <p>I also know, that I can wrap those functions and create my own wrapper like: </p>
  
  <pre><code>function myHtmlize($str)
  {
    return htmlspecialchars($str, ENT_COMPAT, 'UTF-8');
  }
  </code></pre>
  
  <p>I also, don't like this solution.</p>
  
  <p>I really want to tell PHP, that by default take 'UTF-8' as the character set. Not 'iso-8859-1'.</p>
  
  <p>Is it possible?</p>
