Problems with mb_eregi()

What steps will reproduce the problem?
1. include 'phpQuery.php';
2. phpQuery::newDocument($html_markup);
3. $tabs = pq('a[href="#tab"]');

What is the expected output? What do you see instead?
The output results in the following error:
Fatal error: Call to undefined function mb_eregi() in /path/to/phpQuery.php on 
line 1421

What version of the product are you using? On what operating system?
Version 0.9.5 on CentOS

Please provide any additional information below.
According to the PHP manual: http://php.net/manual/en/function.mb-eregi.php
It appears this function is experimental hence I believe a lot of PHP installs 
do not use it. It would be ideal if this script either didn't use it, or 
supported an alternate method if mb_eregi is not a defined function.
