import i3

"""
Py3status plugin - shows current window title.
Requires:
- i3-py (https://github.com/ziberna/i3-py)
# pip install i3-py
If payload from server contains wierd utf-8
(for example one window have something bad in title) - the plugin will
give empty output UNTIL this window is closed.
I can't fix or workaround that in PLUGIN, problem is in i3-py library.
