C++ - How to convert String to wchar_t (Cyrillic)

Question

I need to convert a string to a wchar_t. I have tried a lot of different approaches, but I keep having problems with Cyrillic text. When using wcout to debug, I keep getting wrong output, but when just using Latin characters, no problems arise.

So how can I convert a string containing Cyrillic characters to a wchar_t?

upd: I found the problem, I made a mistake when used wcout to debug, I all time was getting wrong output. But i manually rechecked character codes and it is realy UTF-16. I dont know how to make correct output UTF-16 into console by wcout, but it is not so important for me.

Why do you need `wchar_t` on Linux? What's wrong with UTF-8? — Cody Gray - on strike, Jul 01 '16 at 19:45
i have external library which use wchar_t as input parameters. — Dmitriy Nikulin, Jul 01 '16 at 19:49
I am not an expert on C++, but I don't agree this is a bad question. The question is quite clear: How do I convert one type to another properly. — Joeytje50, Jul 01 '16 at 19:55
What have you tried? Have you tried creating a `std::wstring` from the string then going to a `wchar_t`? — Thomas Matthews, Jul 01 '16 at 20:27

First you also need to know size of wchar_t that that library requires. It may be 16 or 32 bits on different systems. Then you can use std::wstring_convert::from_bytes. This SO answer can also be useful for you.
