I think about something else : if you use pipe redirections AND that you'll
have a chance to write some special unicode characters, python will raise a
UnicodeDecodeError because python2 (no problem with python3) will detect
that the output is not a terminal and will try to convert all string
printed to ascii.
The trick is to export a special variable before executing your fab command
:
*export PYTHONIOENCODING=utf_8*
If you want to try this behavior, this is what you can test. Create a
python script :
#! /usr/bin/env python2
> # -*- coding: UTF-8 -*-
>
print("été")
1) First try executing your code as usual:
*./filename.py*
Everything is OK (if your terminal and locales are in unicode)
2) Than execute your code with pipe redirection:
*filename.py > a_file*
You'll get a unicodedecodeerror.
3) export the special variable and redirect the stdout.
*export PYTHONIOENCODING=utf_8 *
*filename.py > a_file *
It should be OK.
