Thank you so much Mike, you gave me the start I needed! It works now

Just for the record this is what I put in my styles.css

.woocommerce-breadcrumb {
    font-family: 'FontAwesome';
}
.woocommerce-breadcrumb a:first-child:before {
    content: "\f015"
}

And this code in my functions.php

add_filter( 'woocommerce_breadcrumb_defaults', 'jk_change_breadcrumb_home_text' );
function jk_change_breadcrumb_home_text( $defaults ) {
    // Change the breadcrumb home text from 'Home' to a single space
	$defaults['home'] = ' ';
	return $defaults;
}
