Default Fatal Error after 4.2.5 upgrade

Hello after upgrading a site to vBulletin 4.2.5 we now have a blank white page with a fatal error.

Code:
Fatal error: Call to undefined function mb_detect_encoding() in /home/XXXXXXX/public_html/forum/includes/functions.php on line 729
The code on and around that line deals with the mbstring.

Code:
	// We need to replace unicode no-break space
	if (mb_detect_encoding($text) == 'UTF-8')
	{
Any one know how to fix this? From some research I've found info about enabling the mbstring on the server. Will that fix this issue?
