Better performance, more reliable, completely self contained,
more validation and full backwards compatibility.

Nasty strings includes html entities and
non-breaking spaces followed by spaces which makes
very hard to find these strings in the DOM html,
this patch keeps the non-breaking spaces and all
the nasty characters, but leaves them isolated from
other regular spaces. It swaps the strings to HTML before
finding elements in the HTML that matches that contents.
