I have a text dump of a postgresql database and I want to find out if there are any characters that are not standard keyboard characters. Is there a way to use regex to do this without doing a character by character scan of a 5GB file. I want to know where any character that is not one of these is in the file: a-z A-Z 0-9 [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]&*()[]{};:'",.<>/?|\> &*()[]{};:'",.<>/?|\
Thanks in advance Tony Heal
