I've tried this:

$validate($num(%track%,2)-%title%,-)

which converts all invalid characters to "-"

Is there anyway to modify this so it converts "/" to "-" and "?" to "¿" and ":" to ";"

This would match the procedure used by dBpoweramp CD ripper, which would make things nice and tidy.

Thanks in advance.
