Use default Python file encoding during test / release process

[lukebakken]

Unexport vars related to encoding, ensure files are opened with utf-8 when necessary.

Fixes #476 (CLIENTS-864)
Addresses #474

@javajolt this was an interesting issue

@lukebakken I should be able to test this by setting my default lang to something crazy like ANSI_X3.4-1968 and everything should work, right?

[lukebakken]

That's one way, but if you use the Makefile targets it will ensure any environment vars that set lang will be unset. That way you'll use whatever the default is for your Python interpreter.

[lukebakken]

@javajolt - do you have any set in your env? What is the output of these commands?

declare -x | fgrep LC_
echo $LANG

The above would output a lot of variables since Arch Linux sets them all to be UTF-8

[hazen]

declare -x LANG="en_US.UTF-8"

[lukebakken]

OK so the Makefile will unexport that and Python will use whatever its default is.

Seems to work fine
