[New-bugs-announce] [issue30019] IDLE got unexpexted bahavior when trying to use some characters

[David E. Franco G.]

New submission from David E. Franco G.:

wandering for the internet I fount some unicode character in a random comment, and just for curiosity I wanted to use python (3.6.1) to see their value, so I copy those characters and paste them in IDLE, and in doing so it just close without warning or explanation.

the character in question are: 🔫 🔪
(chr(128299) and chr(128298))

then I put them in a script 

    text = "🔫 🔪"
    print(text)

and try to load it but instead it open a new empty scrip, again without apparent reason, which for some reason I can't close, I needed to kill the process for that.

I try the same with the IDLE in python 2.7.13 for the first one I got

    Unsupported characters in input

which at least is something, and changing the script a little

    # -*- coding: utf-8 -*-
    text = u"🔫 🔪"
    print(text)

it work without problem and print correctly. 

Also opening the script in interactive mode (python -i myscript.py) it work as expected and I get their numbers (that I put above).

So why is that? and please fix it.
