It would probably be because one of the (telnet) streams (or both), are not put
into "binary mode" - and thus the telnet client or server is interpreting some
of the binary chars that would be sent.

As per the wikipedia:
https://en.wikipedia.org/wiki/Telnet

"Another difference between Telnet and other TCP terminal clients is that
Telnet is not 8-bit clean by default. 8-bit mode may be negotiated, but octets
with the high bit set may be garbled until this mode is requested, as 7 bit is
the default mode."
