content coming from MS Office clipboard pastes generally contain
characters that are encoded wrong, and do not display correctly in web
pages unless they have very relaxed doctypes. The function I generally
use is:

function removeMSCrap($crap)
{
	$find = Array(chr(128), chr(133), chr(8226), chr(145), chr(8217),
chr(146), chr(8220), chr(147), chr(8221), chr(148), chr(8226), chr(149),
chr(8211), chr(150), chr(8212), chr(151), chr(8282), chr(153), chr(169),
chr(174));
	$replace = Array("&euro;", "&#133;", "&#8243;", "&#039;", "&#039;",
"&#039;", "&#039;", "&#034;", "&#034;", "&#034;", "&#034;", "&#149;",
"&#149;", "&#150;", "&#150;", "&#151;", "&#151;", "&#153;", "&#153;",
"&copy;", "&reg;");
	
	$roses = str_replace($find, $replace, $crap);
	return $roses;
}
