Appears not to like some unicode characters in titles

[talwrii]

Here is my attempt at a small reproducible example:

git checkout upstream/master; git show-ref HEAD; rm -rf venv; virtualenv -p python3 venv ; venv/bin/pip install i3-py &&  xterm -e 'echo -ne "\033]0;hë☺llo\007"; read' &  sleep 10; venv/bin/python3 quickswitch.py; venv/bin/pip freeze  ; venv/bin/python --version
HEAD is now at 0f19f64... Merge pull request #19 from adiog/master

Interesting! I've had no problems with unicode on my box for a long time, so maybe it's the particular unicode char use? Cheers for the bug report. I may be able to take a look at it during the spring festival. We can go about merging your --current request after that's taken care of.

so maybe it's the particular unicode char use

So using ë didn't hit the bug. But a unicode smiley face (☺) did.

I'm not sure what the difference is. The smiley face is three bytes long... perhaps this makes a difference.
