I built an offline Web app (at www.chirp.com) that caches itself when bookmarked on the desktop.

I'm using an '&' symbol with HTML5 and UTF-8 in my site's <title>. Google shows the ampersand fine on its SERPs, as do all the browsers in their titles. http://validator.w3.org is giving me this: & did not start a character reference.
