Strange symbols on page [closed]

That’s a font-awesome icon being added with a pseudo-element.

Here’s the css that’s doing it:

#sidebar ul:not(.social-widget) > li:before, article ul > li:before {
    content: "\f0da";
    font-family: 'FontAwesome';
    display: inline-block;
    margin: 0 5px 10px 1px;
    opacity: 0.7;
}

Using: article .news-container ul > li:before{display:none} should get rid of it.
