This situation seems to be caused by the eric6config.py file having been written by 
a non-compatible Python version. The filesystem encoding on Windows was changed 
from 'mbcs' to 'utf-8' with Python 3.6. According to the given error, the paths 
contained in the file are encoded with 'mbcs'. This leads to the observed issue 
upon import.

In general it is not a good idea to install Python in a path containing such 
"strange" characters.

The next release of eric will be able to ignore such situation and carry on 
installing/updating.

Hi, first of all thank you for the program!

I am trying to install in Windows 10, my user name is "César" with an 
accentuated character in the middle.

Installation in MS-console shows bad the metachar and so the install script 
complains:

Traceback (most recent call last):
  File "install.py", line 2089, in <module>
    main(sys.argv)
  File "install.py", line 2017, in main

    from eric6config import getConfig
