Search error out of the blue

[tloosle]

I beleive this error may be tied to an upgrade to php 5.4

 

 11:25:42 US/Mountain] PHP Warning:  preg_replace(): Compilation failed: disallowed Unicode code point (>= 0xd800 && <= 0xdfff) at offset 1829 in /home2/booster/public_html/thebooster.com/shop/classes/Search.php on line 103

 

 

I have edited Search.php and always get the same results.  Removed the xd800 as refered to in other posts and yet the xd800 always shows in the error_log.

 

Anyone have a solution for this?

 

thanks
