Icons not showing in custom header widget area

Your theme’s font is overriding the font used in the plugin to make the icons.

Awesome . )! Thanks a lot!
Any idea how to fix that?

In other widget areas SSI will show correctly, but not in header.
This is the code in header.php:

//Get Google Webfont
	$pp_font = get_option('pp_font_family');
	$pp_font = urlencode($pp_font);
	if(!empty($pp_font))
	{
		wp_enqueue_style('google_fonts', "https://fonts.googleapis.com/css?family=".$pp_font."&subset=latin,cyrillic-ext,greek-ext,cyrillic", false, "", "all");
	}
	else
	{
		wp_enqueue_style('google_fonts', get_stylesheet_directory_uri()."/css/gfont.css", false, "", "all");
	}
	//End Get Google Webfont

Check the header specific css styling – not the php.

Not a plugin specific issue here, just need to ask the theme author how to override that font.
