Why should we NOT use sys.setdefaultencoding("utf-8") in a py script?
encoding, python, python-2.x, sys, utf-8
Solution
As per the documentation: This allows you to switch from the default ASCII to other encodings such as UTF-8, which the Python runtime will use whenever it has to decode a string buffer to unicode.
This function is only available at Python start-up time, when Python scans the environment. It has to be called in a system-wide module, `sitecustomize.py`, After this module has been evaluated, the `setdefaultencoding()` function is removed from the `sys` module.
The only way to actually use it is with a reload hack that brings the attribute back.
Also, the use of `sys.setdefaultencoding()` has always been discouraged, and it has become a no-op in py3k. The encoding of py3k is hard-wired to "utf-8" and changing it raises an error.

Problem
I have seen few py scripts which use this at the top of the script. In what cases one should use it? ``` import sys reload(sys) sys.setdefaultencoding("utf-8") ```
