Typically you use MultiByteToWideChar() for any input strings and then
WideCharToMultiByte() for possible output strings. You can look at
shlwapi/path.c and other files in there to see how this is usually done.

Depending on the place where you do it, it might be preferable to use
dynamically allocated buffers instead of using stack space as Wine is
already using quite a lot of stack. Principle:

    WCHAR *textW;
    INT countW = MultiByteToWideChar(CP_ACP, 0, textA, -1, NULL, 0);
    if((textW = HeapAlloc(GetProcessHeap(), 0, countW * sizeof(WCHAR))))
    {
        MultiByteToWideChar(CP_ACP, 0, textA, -1, textW, countW);

        /* Do the Widechar call */
  
        HeapFree(GetProcessHeap(), 0, textW);
    }
