          Thorn (Þ, þ) and Ash(Æ, æ) are substituted by the digraphs
          'th' and 'ae' respectively. Wynn(Ƿ, ƿ) and Eth(Ð, ð) are replaced
          by 'w' and 'd'.
  
          Examples:
  
              >>> Word('ġelǣd').ascii_encoding()
              'gelaed'
  
              >>> Word('ƿeorðunga').ascii_encoding()
              'weordunga'
