// Similar to std::ifstream/ofstream, but takes char16ptr_t on Windows.

// Until C++17, std functions can only take char* filenames. So Unicode
|
|
// filenames were lost on Windows. To address this limitations, this wrapper
|
|
// uses proprietary wchar_t* overloads on MSVC, and __gnu_cxx::stdio_filebuf
|
|
// extension on MinGW. Once we can use C++17 filesystem API everywhere,
|
|
// we will be able to avoid this wrapper.
