around this issue Assuming that the input string in your example (おはよう) is a UTF-8 encoded (which it isn't, by the looks of it, but let's assume it is for the sake of this explanation :-)) representation of a Unicode string of your interest, then your problem can be fully solved with the standard library (C++11 and newer) alone.
The TL;DR version:

wish helps you Passing the wstring object to printf is not going to work. Rephrase the second prinf line as
code :
printf("This prints nothing: \n%S", responseHeaders.c_str());

around this issue You're using wprintf. This function cannot accept a std::wstring. The primary reason that you should never, ever, use printf and friends or any variable arguments function is that they are completely un-type-safe, and cannot cope with non-POD types in addition- including any C++ Standard library type.
A C++ IOstream would function perfectly correctly here.

Hope that helps I have the following code. , You should not need to create a std::wstring for this:
code :
wchar_t path[MAX_PATH +1] = {0};


std::wcout << path;
