I am testing the CGI solution now, and it may do the trick. Better would
even be bzipped data.

I essentially get one shot to pass a complete file to a remote socket
connection, and want to do it in the neatest, most reliable, and even
smallest, fashion.

All ideas will be considered :) As I said I tried various pack, gsub,
Marshall ways, but am not totally satisfied yet.

Thanks for answering.

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?
