The one affectation I have forced on the publisher … are my apostrophe-free elisions. Because I write my scripts to read myself, I don't spell 'don't' with an apostrophe. I spell it 'don't'. We all know the word and it seems foolish to put in an extraneous apostrophe. Punctuation marks are devices we use to make the meaning of sentences clear. There is nothing confusing about a word like 'don't' printed without an apostrophe to indicate an omitted letter.
