<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">written characters</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for script that I've seen before include "Text of play, film etc" , "Hand" , "Handwriting, play text" , "Printed text" , "Performance text" .)
