Hostname containing Unicode characters makes pygenie/utils.py error out

[artwr]

The "offending" line is https://github.com/Netflix/pygenie/blob/master/pygenie/utils.py#L34-L40

Even when importing unicode literals, it seems like socket.getfqdn() returns a str instead of a unicode, and the concatenation fails if the hostname contains a unicode character.

With newer Mac OSX, it seems the hostname is set with a unicode apostrophe by default e.g. "Arthur’s".

steps to reproduce on Mac OSX:

oldhost=$(scutil --get HostName)  # To save your current hostname
scutil --set HostName Arthur’s . # for instance
# Running anything importing pygenie under python 2
python2 -c "import pygenie"

It's more of an FYI, since there is an easy workaround (no unicode in the hostname)
