Thread: User defined literal

Should something like this really work?

Code:

template <char...> double operator "" _\u03C0();

Since \u03C0 is π?

I get an error in MinGW that complains about a stray '\' in my source, yet there are documents online that say this *should* be okay.

edit:

Code:

mingw32-g++ (GCC) 4.8.1
