Issue 4530: IDLE crashes with Japanese text on print command

Just got Python 3.0 final on Windows and was testing out IDLE, and it's
having some issues.

Specifically:
* Options -> Configure IDLE..., General Tab:
  Change Default Source Encoding from None to UTF-8
* Create a new python file and enter a print command
  containing Japanese text.  Save it.  (Saves to UTF-8.)
* Press F5 to run the script.  IDLE crashes.

However, if the default encoding is left as "None", and you create a new
file and allow IDLE to save it as cp932, then it runs with no problem
through IDLE.

Straight Python on a command line is not affected and reads the UTF-8
files perfectly fine.

Attached is a script which crashes IDLE every single time I run it.

Thanks.
