The CGI class solves this problem for you: URL’s need to be escaped as
well.

I may have misread the original problem description, but did you not
say “…convert it into a single line string with no characters
readable in it, (such as \n, \t, etc.) …” ?
Did you mean you need unprintables converted, or that you wanted to
end up with a string such that no characters in it are “readable”?
The solution given is for the first one, but normal printable chars
are left untouched with CGI; is this what you wanted?
