Unicode in the Preprocessor

Hello.

I decided to make my code look better by the following trick:

#include <iostream>

#define [e]le[/e] <=
#define [e]ge[/e] >=
#define [e]equiv[/e] ==
#define [e]rarr[/e] ->
#define [e]ne[/e] !=

struct test
{
	double a,b;
};

int main(int const argc, char const *const *const argv)
{
	test *x = new test;
	x [e]rarr[/e] a = 0.5;
	x [e]rarr[/e] b = 1.0;

	if( x [e]rarr[/e] a [e]le[/e] x [e]rarr[/e] b ) std::cout << "Good" << std::endl;
}

This compile and works well. But I am worry about is this comply with C++ standard??
