py3: use encoding.environ in ui.py

Using source transformer we add b'' everywhere. So there are no chances
that those bytes string will work with os.environ on Py3 as that returns a
dict of unicodes. We are relying on the errors, even though no error is raised
even in future, these pieces of codes will tend to do wrong things.
if statements can result in wrong boolean and certain errors can be raised
while using this piece of code. Let's not wait for them to happen, fix what is
wrong. If this patch goes in, I will try to do it for all the cases.
Leaving it as it is buggy.
