[issue13153] IDLE crashes when pasting non-BMP unicode char on Py3

[Ezio Melotti]

Ezio Melotti added the comment:

0xed is the start byte of a 3 bytes sequence (i.e. a BMP char), and it should be followed by two continuation bytes.

For some reason the traceback you pasted is missing the last part, that might provide some insight.  It could be one of these:
>>> b'\xed'.decode('utf-8') # not enough continuation bytes
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xed in position 0: unexpected end of data
>>> b'\xed\x7f'.decode('utf-8') # not a valid continuation byte
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xed in position 0: invalid continuation byte
