    No, that is not the requirement. It is:

    bytelength(f(s)) <= 2*bytelength(s)

    Thanks for trying to help, Jill. Take a break.

    I said performance reasons. Determining it exactly costs more than strlen of
    the source string. And when you know the max size of the source string, you
    don't even need to strlen it.
