a non-ASCII byte in the format string.

Document also the encoding.

os.listdir(str) always returns unicode and it can return non-ascii filenames
even if supports_unicode_filenames is False.

the value with filesystem encoding and surrogateescape (instead of utf-8 in
strict mode).

Py_Main() uses _Py_wchar2char() + PyUnicode_FromWideChar() instead of
PyUnicode_DecodeFSDefault(), because the PyCodec machinery is not ready yet.

Fix a crash if Python is compiled in pydebug mode.

os.environ.data was a str dict in Python 3.1. In Python 3.2 on UNIX/BSD,
os.environ.data is now a bytes dict: mark it as protected to avoid confusion.

environment variable to set the filesystem encoding at Python startup.
sys.setfilesystemencoding() creates inconsistencies because it is unable to
reencode all filenames in all objects.

namespace if it occurs as a free variable in a nested block.  This limitation
of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).

This sample was valid in 2.6, but fails to compile in 3.x without this change::

   >>> def f():
   ...     def print_error():
   ...        print(e)
   ...     try:
   ...        something
   ...     except Exception as e:
   ...        print_error()
   ...        # implicit "del e" here


This sample has always been invalid in Python, and now works::

   >>> def outer(x):
   ...     def inner():
   ...        return x
   ...     inner()
   ...     del x

There is no need to bump the PYC magic number: the new opcode is used
for code that did not compile before.

Use it here again.

or not.  Also, the "backslashreplace" error handler now joins surrogate
pairs into a single character on UCS-2 builds.
