[issue28180] sys.getfilesystemencoding() should default to utf-8

What I propose is non't use mbstowcs, like __ANDROID__

wchar_t*
Py_DecodeLocale(const char* arg, size_t *size)
{
#if defined(__APPLE__) || defined(__ANDROID__)
    wchar_t *wstr;
    wstr = _Py_DecodeUTF8_surrogateescape(arg, strlen(arg));


On Linux, command line arguments and filepath is just a byte sequence.
So using UTF-8:surrogateescape from during startup should works fine.

Am I wrong?
