I\'m using an \'&\' symbol with HTML5 and UTF-8 in my site\'s . Google shows the ampersand fine on its SERPs, as do all the browse
&
if & is used in html then you should escape it
If & is used in javascript strings e.g. an alert('This & that'); or document.href you don't need to use it.
alert('This & that');
If you're using document.write then you should use it e.g. document.write(this & that)
document.write(this & that)
this & that
