some combinations of installations of Python, operating system, and Tcl/Tk/ActiveState will cause binding events to crash the app

interpreter throws this error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfe in position 0: invalid start byte

finally fixed this error .. it requires overwriting (at least) one line in the tkinter module for python

on my machine, the relevant file lives at /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter/__init__.py

in this file, you can find a variable called _subst_format defined on lines 1378-1380 that contains a tuple of percent encodings ... if you change %A -> %D, this fixes the problem (for me)

i've included a try-catch block to handle this error and instructions for fixing it if it does occur ... god help any users who require more support than this.

rumor has it that this bug is fixed in Tcl/Tk 8.6, but that doesn't bundle with python3.6, so you could try building it from source if you'd like, but this seemed like a (slightly) easier fix
