In Python 3, the built-in open() function sports a fancy encoding=
parameter like that.

for line in open("tmp.txt", encoding="utf-8"):

If you can, I would recommend using Python 3 for all this kind of
thing. The difference may not be huge, but there are all sorts of
little differences here and there that mean that Unicode support is
generally better; most of it stems from the fact that the default
quoted string literal is a Unicode string rather than a byte string,
which means that basically every function ever written for Py3 has
been written to be Unicode-compatible.
