Part of the reason I'd like to know is I've been using tabs as my separators, (due to some of the salts including ':'), because I'd never thought that people could even use a tab in a password field. Heck, I actually switch between the username and password fields in a lot of places by hitting tab since it automatically moves me to the next field.

Is there a way to specify specific non-printables in rules? Say I want to prepend a TAB, or match a TAB and replace with a BEL, just as examples. The documentation does not mention any way to do this. In external modes, I can use 0x09 of course. A generic way to specify *any* non-printable, like \x09 or something to that effect, would be very usable. I thought of placing this functionality in the preprocessor but keep in mind you may want to use it in a PP list (like [0-9\x09] for digits + TAB) too. Or even a CR or LF for that matter. I haven't looked into it yet, any comments off the top of your head? Regards MPI -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
