Font char does not render in Chrome on Win7

[ewohnlich]

This guy here https://github.com/plone/plonetheme.barceloneta/blob/master/plonetheme/barceloneta/theme/less/barceloneta-compiled.css#L2934 I can't speak for other versions of Windows but it doesn't work on Win7 in Chrome. It's fine in Firefox. It seems that "⟩" (should be same unicode) doesn't even work in some font families here, more info: http://stackoverflow.com/questions/23139696/why-html-entity-doesnt-work-on-win-chrome

I added the following to my css and it seems to work in all environments I've tried:

.portletNavigationTree .portletContent > ul > li > a:hover::after {
    font-family: Cambria Math;
}
