Why does the GetFileInformationByHandle function not work on files with Russian names?

Question

C++ / C#

When calling GetFileInformationByHandle, the GetLastError function returns ERROR_INVALID_HANDLE when working with files whose names are written in Russian. Has anyone come across something similar? Suggest a solution.

Answer 1

show the full code. Apparently your handle is invalid. It turns out the file did not open.
