That may be true for iostreams and the serialization library,
but it's not true with respect to delimiters for use with
Boost.Asio's read_until function.

Is there any character that is guaranteed not to appear in the
output of a text archive? I'm guessing there isn't one, so I
would recommend that Christian use the approach of the
serialization example included with Boost.Asio, which is to have
a fixed size message header containing the length of the message
body.

Cheers,
Chris
