I use JCalPro and the responsive calendar theme displays what should be icons as text. Per the calendar developer : "The inspired template depends on twitter bootstrap being loaded by the template as default, it appears your template is not loading or incompletely loading it.
Inspired will never show the same icons as the default templates as it is a completely different responsive design.
It will however have a toolbar if bootstrap is loaded properly "
Is the News template capable of supporting this?
