While this seems to work most of times, I meet a malfunction (data not
preserved) if the stream ends with a line-feed (a byte whose value is
10). When it is, this last byte seems to be dropped from the stream,
which cause troubles if the binary format is expecting it. This occurs
only when it exactly ends with this byte, and it is Ok if this byte is
followed by a byte whose value is 0 (as an example). It does not occur
when the stream ends with a byte whose value is that of the carriage-
return (13).
Finally, this does not really turn the stream into a binary stream,
and some interpretations remain.
