Comment (by dd32):

 > if ( ! $term || ( 1 === strlen( $term ) && preg_match( '/^[a-z]$/i',
 $term ) ) )

 That doesn't sound right to me, specifically, the strlen() component.
 A non-ascii character will always be >1char (unless mbstring overloading
 is enabled, but lets not go there) so that preg_match is only checking to
 see if a non-a-z ascii character is present.
