[issue5256] rlcompleter adds builtins when custom dict is used

[Armandas]

New submission from Armandas :

When custom dictionary is used to create a completer, rlcompleter still
uses __builtins__.__dict__ to search for completions (rlcompleter.py,
global_matches()):

for nspace in [builtins.__dict__, self.namespace]:
...

This behaviour may sometimes be unwanted. It would be nice to have an
option, which when set would tell completer to only use provided dictionary.

[issue35541] CLI error when .python_history contains unicode characters

[Armandas]

New submission from Armandas :

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

  File

 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 

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.
