BTW, I was scratching my head about this, and had to hit the books. There is special handling for '-' inside [^...] expressions. The '-' has to be first or last. Here's a test using Unix grep - which implements the same POSIX REs as Witango:

Some other characters are allowed and I won't be surprised if more spring up in the future. This way if & becomes acceptable I can just add it to the keep statement. > EXPR="[^A-Za-z0-9\\/:\-\.]" But I might also have a play around with this for the sake of learning.
