javascript - ReferenceError: TextEncoder is not defined

I'm writing a simple addon in Firefox - 24, on Linux. I get the error:

ReferenceError: TextEncoder is not defined

when I do: var encoder = new TextEncoder(); the function I'm using is:

function write_text(filename, text) {
    var encoder = new TextEncoder();
    var data = encoder.encode(text);
    Task.spawn(function() {
       let pfh =  OS.File.open("/tmp/foo", {append: true});
       yield pfh.write(text);
       yield pfh.flush();
       yield pfh.close(); 
    });
}

In nodejs you can solve with util:

var util= require('util');
var encoder = new util.TextEncoder('utf-8');
