POSIX locale used by mistake
----------------------------
In many cases, the POSIX locale is not really expected by users who get
it by mistake. Examples:
* program started in an empty environment
* User forcing LANG=C to get messages in english
* LANG=C used for bad reasons, without being aware of the ASCII encoding
* SSH shell
* User locale set to a non-existing locale, typo in the locale name for
example
C.UTF-8 and C.utf8 locales C.UTF-8 and C.utf8 locales

Some issues are real bug in applications which must set explicitly the
encoding. Well, it just works in the common case (locale configured
correctly), so what? But the program "suddenly" fails when the POSIX
locale is used (probably for bad reasons). Such bug is not well
understood by users. Example of such issue:
* 2013-11-21: `pip: open() uses the locale encoding to parse Python
script, instead of the encoding cookie
<http://bugs.python.org/issue19685>`_ -- pip must use the encoding
cookie to read a Python source code file
* 2011-01-21: `IDLE 3.x can crash decoding recent file list
<http://bugs.python.org/issue10974>`_
