var leet = new Leet; 

leet.symbols = function () {
	return {
		a: ['@']
	}
};

leet.encode('abc'); // @bc

phrases

var leet = new Leet;

leet.phrases = function () {
	return {
		one: ['01']
	}
};


leet.encode('one2'); // 012

numeric

var leet = new Leet({numeric: true});

leet.phrases = function () {
	return {
		a: ['01']
	}
};

leet.encode('a2'); // 012
