[issue21084] IDLE can't deal with characters above the range (U+0000-U+FFFF)

[wjssz]

New submission from wjssz:

When open a file with characters above the range (U+0000-U+FFFF), IDLE quit without any report. For example, open this file \Lib\test\test_re.py

The below is Traceback info, the last line tells the reason. I just hope IDLE say something before quit, so we can know what happend.

I have checked Python 3.3.5 and 3.4.0, they have the same problem. I didn't find a 3.5 build, so I can't test this problem under 3.5.
