[issue8438] Codecs: "surrogateescape" error handler in Python 2.7

New submission from Ray.Allen <ysj.ray at gmail.com>:

According to PEP 383, the new "surrogateescape" error handler of codecs should begin to appear since Python3.1, but in the trunk I found some code have already used it:


static int
fileio_init(PyObject *oself, PyObject *args, PyObject *kwds){
    stringobj = PyUnicode_AsEncodedString(
		u, Py_FileSystemDefaultEncoding, "surrogateescape");

Obviously, the "surrogateescape" error handler not exists. 

Some test code:
import io

file_name = u'\udc80.txt'
f = io.FileIO(file_name)

When run this piece of code on a machine whose file system default encoding is gb2312, will raise an exception:

LookupError: unknown error handler name 'surrogateescape'

I don't know weather this is a bug?
