title: Composer not working after a clean install on centos 5
body: <p>We've been working with our hoster to install <code>composer</code> on a <code>centos 5</code> with <code>php 5.3.9</code>, and though we get no installation errors, running composer with any command always gives us the following:</p>
  
  <pre><code>-bash-3.2$ composer help install
  
  ??+?-bash-3.2$ 
  </code></pre>
  
  <p>always this funny <code>??+?</code> response.</p>
  
  <p>This also happen when I download a composer.phar manually, and if I run <code>composer.phar</code> over <code>php</code>. Always the same issue. The provider technicians tried to install it with admin privileges and they also get this error. any ideas?</p>
