There is no such compressor.
It is impossible to generate an algorithm that will compress any input; if
any input stream leads to a shorter output stream[1] some input streams
will necessarily lead to longer lones :-(
A "universal" compressor fails the Counting Argument.
Vic.
[1] i.e. I'm ignoring the trivial (and useless) solution of just copying
input to output, thereby achieving zero compression and zero expansion on
all streams.
