Opening a file with name in UNICODE format

[Ajay L D]

Hi, I am trying to open a file, whose name is in UNICODE string with a Byte-order Mark (BOM). How do I open such files? The CFile class fails to recognize such a name. Thank you. AJ

#include <fstream>
wchar_t file_name[] = L"hello.txt"; // ... Your file name source.
// std::fstream f(file_name, std::ios::in | std::ios::out);
std::wfstream f(file_name, std::ios::in | std::ios::out);

Thank you for your reply. But an existing file with Byte-order Mark (Ex: FFFE), will not open with the above code.

I just made a file with the mark EF BB BF in the beginning three bytes of the content, and the content is in Chinese. I use the below code, and it can open and load data into fstream variable. (Sorry for my typo in last reply. Note the "w" of the type name.)

std::wifstream file(file_name, std::ios::in | std::ios::binary);
