in reply to Find what characters never appear

Is the available character that you find guaranteed to never be used? This sounds like a use case for one of the CSV modules.

    I agree.

      I second your agreement, especially since the 11th corollary of Finagle's Fifth Law of Dynamic Disappointment states that "any file that is guaranteed not to contain a given character at the current moment is guaranteed to contain that character at some future moment, and probably sooner rather than later".
