Copy files with widestring path in C++

Question

I'm having some trouble using wchar_t* strings for copying a file, how do I open them in C/C++ I need to use wide chars because the filenames are in unicode with different foreign languages.

Thanks in advance.

You need to distinguish between unicode file names, and unicode file content. Unfortunately, standard C/C++ only deals with wchar_t for file content. Using wchar_t for file names is platform-specific (hence Brian Bondy's question for clarification).

On Windows, you have to use Microsoft-specific API (such as _wfopen) to open a file with a wchar_t name. On all other systems, you need to use char as the data type for file names.
