Many of my links have material icons in tags inside the link. Now, Google has indexed my page with site-links that include the text/ligature from that material-icons tag, so a link might say "shopping_cart Shop Now" for example.
Everything already displays correctly when browsing the site, but it's just in google's search results that the page titles look ridiculous.
<li>
<a href="/feed.php">
<i class="material-icons icon">shopping_cart</i>
<span>Shop Now</span>
</a>
</li>
I would not expect the text "shopping_cart" to appear when Google indexes these page titles for site-links. How can I tell Google to stop doing that?
