It's a ParseTuple converter: decode bytes objects to unicode using
PyUnicode_DecodeFSDefaultAndSize(); str objects are output as-is.

 * Don't specify surrogateescape error handler in the comments nor the
   documentation, but PyUnicode_DecodeFSDefaultAndSize() and
   PyUnicode_EncodeFSDefault() because these functions use strict error handler
   for the mbcs encoding (on Windows).
 * Remove PyUnicode_FSConverter() comment in unicodeobject.c to avoid
   inconsistency with unicodeobject.h.

 * Use _Py_wchar2char() in _wstat() and _Py_wfopen()
 * Document _Py_char2wchar()

at interpreter startup before importing any non-builtin modules.
Should fix #9589.

compilers (which are detected by the configure script).  They can still
be disable selectively by specifying --without-computed-gotos.

Also add myself as assignable for email issues.

Omit the filename to avoid enconding issues, especially with non encodable
characters in the Python full path.

Similar to PyErr_WarnEx() but use PyUnicode_FromFormatV() to format the warning
message.

Strip also some trailing spaces.

test_imp fails on Linux with C locale because TESTFN_UNICODE is not encodable
to ascii.

This function is only by imp.find_module() which does return the filename in a
separated variable.

 * On non-Windows OSes: the constructor accepts bytes filenames
   and use surrogateescape for unicode filenames
 * On Windows: use GetFileAttributesW() instead of GetFileAttributesA()

 * Use 0xff byte on non-Windows OSes
 * mbcs is now really strict by default: i closed the issue #850997, so use the
   filesystem encoding and not Latin-1
 * Rename TESTFN_UNICODE_UNENCODEABLE to TESTFN_UNENCODEABLE

BadZipfile error is raised if it doesn't match (as used to be the
case in Python 2.5 and earlier).
