Not sure about IE, but it looks like Webkit somehow messes up \\ at the end of
the before content no matter what.  |content: "\\m";| shows a backslash
followed by an 'm', but |content: "whatever\\"| shows nothing.

And even more clearly, something like this:

 <style>.a:before { content: "m\\"; } .a { content: "o\\" }</style>
 <div>a:'<span class="a">'</span></div>

Renders as:

 a:'m\"; } .a { content: '

in Webkit.  So it looks like the \\ is somehow managing to escape the '"' in
Webkit's parser.
