I remember there was a guy on compression forums who was very annoyed at this waste of coding space. If you're doing compression, shouldn't you make sure every encoded file decodes to a distinct output? He thought so, and made bijective versions of Huffman coding, arithmetic coding, LZ coding and (even more impressive) the BWT transform known from bzip2.

He was a bit crazy, but I liked that guy. Rest in peace, David A. Scott. Maybe there will be new uses for making all compression bijective over all byte streams.
