Unexpected output: "W: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: T"

Issue or Feature

I tried to draw a string on the canvas, but I got very weird error and program terminated immediatelly.

Steps to Reproduce

'use strict'; // Optional

var ctx = new (require('canvas').Canvas)(1, 1).getContext('2d');
ctx.font = '1px arial';
ctx.fillText('\u8081', 0, 0);

Nothing has been drawn to the canvas (see my comment below) and the following text has been output to the console:

> node index.js
W: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: TW: T

Whatever is going on here, I am hundred percent sure it is not working as expected.
