typedef basic_filebuf<wchar_t> wfilebuf;
File stream buffer (wide)
Stream buffer to read from and write to files using wide characters.
This is an instantiation of basic_filebuf with the following template parameters:

| charT | wchar_t | Aliased as member char_type |
| traits | char_traits<wchar_t> | Aliased as member traits_type |
