Hi there,
you could use some CSS like this to add ‘something’ before the title:
h2.entry-title:before {
content: 'x';
left: -1em;
position: relative;
z-index: 1;
}
You can replace the x with a HTML unicode to use one of the built in icons, see here:

Or any other icon library you may choose to install.
Or instead you can write the property for use with an image: content: url('url-to-my-image');
