Copyright symbol line height – Javascript functions solution?

can you try this in your child-theme functions.php:

function wrap_copyright_text_with_sup(){
?>
<script>
(function($) {
$(document).ready(function() {       
     $('body :not(script)').contents().filter(function() {
        return this.nodeType === 3;
        }).replaceWith(function() {
            return this.nodeValue.replace(/[™®©]/g, '<sup>$&</sup>');
     });
});
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'wrap_copyright_text_with_sup');

it includes TM and ® and ©

PS: Node.TEXT_NODE (3) ⇒ The actual Text inside an Element or Attr.

PPS: Yes me too i’m happy that Rikard could help ;)
