Default encoding and error handler:
* if Py_SetStandardStreamEncoding() has been called: they have the
highest priority;
* PYTHONIOENCODING environment variable;
* The UTF-8 Mode uses UTF-8/surrogateescape;
* If Python forces the usage of the ASCII encoding (ex: C locale
or POSIX locale on FreeBSD or HP-UX), use ASCII/surrogateescape;
* locale encoding: ANSI code page on Windows, UTF-8 on Android,
LC_CTYPE locale encoding on other platforms;
* On Windows, "surrogateescape" error handler;
* "surrogateescape" error handler if the LC_CTYPE locale is "C" or "POSIX";
* "surrogateescape" error handler if the LC_CTYPE locale has been coerced
(PEP 538);
* "strict" error handler.
Supported error handlers: "strict", "surrogateescape" and
"surrogatepass". The surrogatepass error handler is only supported
if Py_DecodeLocale() and Py_EncodeLocale() use directly the UTF-8 codec;
it's only used on Windows.
initfsencoding() updates the encoding to the Python codec name.
For example, "ANSI_X3.4-1968" is replaced with "ascii".
On Windows, sys._enablelegacywindowsfsencoding() sets the
encoding/errors to mbcs/replace at runtime.
