SVG unicode support

Hi

I have an svg font file ( not svg ) :

<glyph glyph-name="somename" id="glyph2456"   unicode="&#xe601;" d="M..." />
this red value is use by CSS pseudo element http://css-tricks.com/css-content/

in phpstorm :it appear an icon  in Inkscape ( SVG Font Editor); it appear as little boxes with tiny "e600" inside.
in Notepad++, it appear  with a  little box [].


Is there a way to have access to the icon ( read mode) and real value (edit mode) for this value using phpstorm ?
