I've worked with numerous OCR scans that dropped the EMDASH. From reading the text it looked like missing commas/full-stops, but the PDF of the original book revealed the missing emdashes.
Sorry for the late reply, I am having major problems with Calibre at the moment.
Yes I am comparing to an original text and there are definite ommissions, but the Regex provided by Perkin has definitely got around the problem.
Thanks for the input though.
