I'm not quite sure why the Linux system doesn't display characters,
although the data is correct. However, it's almost certainly terminal
related: at some point Python has to format the result in a fashion that
can be displayed on the terminal ("in the terminal application" would be
a bit more appropriate to today's implementations, I guess) and your
Linux and Mac systems don't necessarily coincide in their capabilities.
Most Linux setups will be fine, but there are reasons why it might be
restricted to something like, say, only ASCII (accessing via telnet or
ssh with restricted negotiation, for example).
You are asking Python to use the __str__ method on the model. Unless you
somehow tell it that the result should be a unicode object, it will
assume a str. Django uses the User.__unicode__ method and UTF-8 encodes
it. The Linux output you're seeing is consistent with this: it's the
UTF-8 encoding of the original string.

This would be consistent with your terminal not supporting something
like UTF_8 output -- or, rather, with Python thinking that the output
has to be displayed in ASCII.
Don't get too hung up on the results of print output (I realise it might
hamper some debugging approaches, but it's the debugging approach that
is causing the problem here, not some bigger issue). There's a big
variable involved -- terminal encoding type -- that isn't present in
normal code execution.
