In linux world, the encoding of path is dependent to FS, that's true:)
Even though at nowadays, major FS are UTF-8 as default encoding.
But in Win32 world, that's different things, the Win NTFS are using
UTF16 for the FS, but under different system locale, (GBK or CP1252)
it's would using different encoding(GBK or CP1252) to open the same file.
That's make the open function useless on win32.
