Searching for a » character in a JavaScript RegExp

How can I sear开发者_开发技巧ch for a » character in a JavaScript regexp?

Code that's not working right now:

var extralinks = new RegExp('»','g');  
div.innerHTML = div.innerHTML.replace(extralinks,'This is special punctuation');  

Grazie!

var extraLinks = /\xBB/g;

look up the ASCII table and escape the character http://www.asciitable.com/
