Can command prompt display unicode characters?

Question

For example:

cout << \"你好\" << endl;

Answer 1

Depends on the operating system and implementation. The currently active C++ standard doesn't even talk about Unicode.

On Windows I believe you can use the wide character versions. Your code would then need to be:

std::wcout << L"ni3 hao3" << std::endl;

However, you might have to specifically enter the Unicode character codes because the codeset you're using to write your C++ source might not be Unicode.
