Total utter bunk. You're thinking of email and news, which had to deal with broken legacy code.

HTTP has *always* been binary clean. It does not encode anything into 7-bit safe anything. The only "encoding" that it ever does is HTTP/1.1's chunked encoding, which is a way to deal with the fact that it might not always know the total length of the data before it starts the transfer; it sends the data in arbitrary-sized "chunks" prefixed by a byte count. It does this to support connection caching in HTTP/1.1; HTTP/1.0 would simply close the connection to indicate end of (binary) data.
