Crash in toggle_comments.py
There are issues with commenting/uncommenting in python files with unicode characters. I obtained the following crash after a tablet hard reset, opening pythonista, and trying to uncomment the 3 highlighted lines via the keyboard shortcut (cmd+/). I do use quite a few unicode chars in my script, such as 𐄙, 𐄚, 𐄛, 𐄜, Ω, and have noticed from some time that it messes up commenting/uncommenting blocks of code, but this is the first actual crash I encounter.
(I don't know how else to attach some pics here)
