Add Filter for Microsoft Word Style elements

remove_word.php

<?php


add_filter('the_content', 'remove_microsoft_word');
function remove_microsoft_word($content) {
		$find = strpos($content,"<style type=\"text/css\">
<!--
 /* Font Definitions */");
	while( $find ) {
		$end = strpos($content,"
-->
</style>",$find);
		$content = substr($content,$end+14);
		$find = strpos($content,"<style type=\"text/css\">
<!--
 /* Font Definitions */");
	}
	return $content;
}

?>

Add to functions.php. Only works well when style elements are at the head of a document.
