Crystal clear.

I don't know why the PSF Mac Python is still compiled against 8.5 
instead of 8.6.  I will open a tkinter issue, even though it will likely 
be closed as 3rd party, both to document the problem and as more 
evidence of the need to change to compiling against 8.6.

PS: About a year ago, someone (you?) said we might see a tk that 
supports the unicode beyond the BMP in 2017.  Is there any development 
in that direction.  I think that this is the tk improvement that IDLE 
most needs.
