New submission from Armandas <jarusaus...@gmail.com>:
OS: Windows 10
Python version: Python 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:05:16) [MSC
v.1915 32 bit (Intel)] on win32
Traceback:
Failed calling sys.__interactivehook__
Traceback (most recent call last):
File "C:\Users\owner\AppData\Local\Programs\Python\Python37-32\lib\site.py",
line 439, in register_readline

line 23, in decode
return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 2:
character maps to <undefined>
How to reproduce:
On a Windows machine, add the following line to your .python_history:
"あ".isalpha()
I believe the issue stems from the fact that the history file is opened with
the "default" encoding, which on windows is cp1252.
