Output unicode symbol π and ≈ in c++ win32 console application

Question

I am fairly new to programming, but it seems like the π(pi) symbol is not in the standard set of outputs that ASCII handles.

I am wondering if there is a way to get the console to output the π symbol, so as to express exact answers regarding certain mathematical formulas.

Answer 1

I'm not really sure about any other methods (such as those that use the STL) but you can do this with Win32 using WriteConsoleW:

HANDLE hConsoleOutput = GetStdHandle(STD_OUTPUT_HANDLE);
LPCWSTR lpPiString = L"\u03C0";

DWORD dwNumberOfCharsWritten;
WriteConsoleW(hConsoleOutput, lpPiString, 1, &dwNumberOfCharsWritten, NULL);
