Hi,
I solved it adding that in the code :
/core/core.php :
update line 581 : $data[] = htmlspecialchars_decode(htmlentities(trim( stripslashes( $shortcode ) ), ENT_NOQUOTES, “UTF-8”));
add line 650 : $content = utf8_encode($content);
This is just a quick fix, spread the word if you think it’s worth it!
Looking forward for th official fix.
Thanks.
