It should show NO BOM.

If you download a file, you can check for the presence of a BOM by doing:

hexdump -n 3 -C filename.jpg

if you see "ef bb bf" you've got a BOM.

to remove a bom, use tail

tail -c +4 bad.jpg > better.jpg

Here's some PHP to test whether the wp-config.php has a BOM:

	$contents = file_get_contents(dirname(__FILE__) . '/wp-config.php');
	if (substr($contents, 0, 3) == "\xef\xbb\xbf") {
		echo 'CONFIG HAS IT!';
	}
