Remove Chinese Characters with Preg_replace?
<p>I am trying to remove chinese characters from string. Tried this but can't get this working. It says:</p>

<blockquote>
  <p><strong>Warning:</strong> preg_replace() [function.preg-replace]: Compilation failed: character value in \x{...} sequence is too large at offset 9 in</p>
</blockquote>

<pre><code>preg_replace('/[^\x{4e00}-\x{9fa5}]+/', '', $string)
</code></pre>

<p>How can I get this working ?</p>
