 Some applications like Aperture, use UTF8 in the IPTC tags. When exported
 images are uploaded to WordPress, the title and description metadata has
 the wrong encoding

 The problem is in [http://phpxref.ftwr.co.uk/wordpress/nav.html?wp-
 admin/includes/image.php.source.html#l197 wp_read_image_metadata], since
 it runs utf8_encode for every field even if it's already utf8

 To check if the parsed iptc is already UTF-8:

 {{{
 $iptc_is_utf8 = isset( $iptc['1#090'] ) && "\x1B%G" == $iptc['1#090'];
 }}}

 Depending on that result, the tags should go through utf8_encode or left
 as they are
