I understand that a single quote should be used when writing /won't/, but it's probably not the first time __YOU_WON_01 hits on /won’t/ with a right single quotation mark.
Apparently this can happen automatically in certain text editors when there are two apostrophes in the same sentence.
I would suggest a second negative lookahead to correct the issue. -Olivier
