You should be able to reproduce the same behavior on PyDev if in your run
configuration you select the encoding of the console to be ascii (run > run

us-ascii).

My guess is that you have the problem because the username has non-ascii
chars -- and you're receiving it as an unicode and not a string... so, you
have to do encode it properly to a string before writing to the connection
(i.e.: username.encode('utf-8') + '\r' -- although the encoding may have to
be a different one and not utf-8).

Cheers,

Fabio
