How to get the current system localization (C++)?

Question

C++ / C#

I would like to get something like Russian_Russia.UTF-8.
auto locale = std::setlocale(LC_ALL, "")
returns what I want on Windows but doesn't return on OSX. On OSX, the result of the operation is "C". (classic encoding as I understand it)
How can I cross-platform get the current language of the operating system?
Is there a solution in boost?
