vegeta encode: can't detect encoding of "stdin"vegeta encode: can't detect encoding of "stdin"

There are some file types like datagram sockets (UDP, SCTP or unix domain at least), or SOCK_SEQPACKET on some systems that preserves message boundaries, but you'd need a different API than read() and write() if you want to allow empty messages, and the reader would have to know in advance the maximum possible size of those messages and allocate a buffer that big to receive it.
