How to dynamically format any trademark sign

With this JavaScript / JQuery code snippet you’ll be able to dynamically format any type of sign on your website. Here’s an example:

Unformatted:

tristankappel®

Formatted:

tristankappel^®

And here’s the snippet the uses regular expressions:

$("body").html(
  $("body").html()
    .replace(/((?!<sup>\s*))&reg;((?!\s*<\/sup>))/gi, '<sup style="font-size: 0.7em">&reg;</sup>') // wrap &reg; if not wrapped yet
    .replace(/((?!<sup>\s*))®((?!\s*<\/sup>))/gi, '<sup style="font-size: 0.7em">&reg;</sup>') // wrap ® if not wrapped yet
);

It will work for any type of sign.

This could also be achieved by a search and replace in the database. But if you want to ensure that every possible future occurrence of a sign like this will be formatted the same way, without forcing your editors to write HTML, this is a good approach until you can do the database search and replace.
