The special character after the date wouldn't affect that regular expression, however any special character BEFORE the date (between "By" and the date) would cause the date not to be grabbed (i.e. "Amount Due By:" or "Amount Due By -" etc.). Use the following regular expression:
Amount\s*Due\s*By\W*(\d{1,2}/\d{1,2}/\d{2,4})
This would grab any date after the phrase "Amount Due By" regardless of if there are or are not special characters following "By"; I've also adjusted the parameters in the date digits so it will grab dates with 1 or 2 digits month/day and 2 or 4 digit year (ex: 9/9/19, 9/9/2019, 09/09/19, 09/09/2019 will all work).
