Any emoji support?

The following code gives me the follwing image output:

```
var Canvas = require('canvas');
var Image = Canvas.Image;
var canvas = new Canvas(1200, 600);
var ctx = canvas.getContext('2d');

ctx.font = '80px HelveticaNeue';
ctx.fillText('Start Here emoji 🍔', 50, 100);

res.setHeader('Content-Type', 'image/png');
canvas.pngStream().pipe(res);
```

Not rendering the emoji. Is this possible?
