I see other have the same issue so its part of the theme, can you help rectify error below:
Document uses the Unicode Private Use Area(s), which should not be used in publicly exchanged documents. (Charmod C073)
and the line it refers to
<a id="advanced_menu_toggle" href="#" aria-hidden='true' data-av_icon='' data-av_iconfont='entypo-fontello'></a><a id="advanced_menu_hide" href="#" aria-hidden='true' data-av_icon='' data-av_iconfont='entypo-fontello'></a> <div id='header_meta' class='container_wrap container_wrap_meta av_icon_active_right av_extra_header_active av_secondary_left av_phone_active_left av_entry_id_4385'>
Hey reefcentraluk!
This is just how the theme encodes the icon font and there isn’t any quick fix we could offer to fix it. On the whole, the theme will never fully validate because of the cross browser support that is in place and some of these kinds of quirks with the html5 spec.
It has no impact on the sites SEO or functionality however.
