The Idle Editor or Idle Python Shell crashes if ` character is typed in. Character looks like an ` with underscore. 

How to repeat this problem:
1. In OSX open any .py file or the Idle Shell with Idle.
2. Switch to german keyboard layout
3. Type the letter by pressing shift and the  +=  button, left of the delete button. (Keyboard hardware layout is US)

I attached only the crash report of version 3.6.3. This issue happens also to all previous versions. I didn't checked with versions higher than 3.6.3.

Info from shell (not crashed yet):
Python 3.6.3 (v3.6.3:2c5fed86e0, Oct  3 2017, 00:32:08) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "copyright", "credits" or "license()" for more information.

See screenshot from character:

without: ` and with underscore: `

(underscore is not shown as text in comment. See screen shot)

This is a duplicate of previous reports.  The problem, visible in the crash report, is that you are using the buggy Apple installed tcl/tk 8.5.9 and missed the upgrade instructions on

Ned, the web page implies that only 8.5.7 is 'not recommended' and lists 8.5.9 as an acceptible 'alternate'.  But empirically, by multiple reports like this, it leads to crashes.  Can we get that page updated?
