Python 3 unicode codec error binding mousewheel in tkinter


I found some references online useful to grasp the problem, it seems to happen on an older version of ActiveTcl (8.5.x).

The solution is to upgrade your version of ActiveTlc to >=8.6 and you can do this in two ways:

  • manually
  • installing the latest version of Python 3.7.1 via the binary package on Python Release 3.7.1
