Hi INADA-san,
This PEP is the result of 2 years of refactoring to simplify the implementation. I agree that bytes string is the native type on Unix. But. On Windows, Unicode is the native type. On Python 3, Unicode is the native type. One key of the simplified implementation is the unique PyConfig structure. It means that all platforms have to use the same types.
I love the idea of using only wchar_t* for PyConfig because it makes Python initialization more reliable. The question of the encoding used to decode byte strings and any possible decoding error (very unlikely thanks to surrogateescape) is better defined: it occurs when you set the parameter, not "later during init".
The PEP adds Py_UnixMain() for most trivial use cases, and PyConfig_DecodeLocale() and PyConfig_SetArgs() for more advanced cases.
Victor
