title: Woocommerce attribute as symbol not text
body: <p>I don't seem to be able to find any information on whether this is possible. Instead of a piece of text as an attribute I would like to display a tick symbol.</p>
  
  <p>i.e. My attribute is called Vegetarian the value is "yes". Instead of displaying the word "yes" I would like to display a tick symbol.</p>
  
  <p>Does anyone know where I could make an edit to achieve this?</p>
