I might be wrong, since I'm new to Qt and never used one of it's QSockets, but I imagine that data is data.

What I mean is, if you make a tcp connection with QTcpSocket and send 8 bytes of data, the other side will recieve 8 bytes of data, untouched.

I think you do not need to worry, it's a convenience class around sockets.
