Building w/ emoji throws exception

[dwbruhn]

I tried your example code, but with emoji:

var builder = require('xmlbuilder');
var xml = builder.create('root')
  .ele('xmlbuilder')
    .ele('repo', {'type': 'git'}, 'test 🐀 here')
  .end({ pretty: true});

console.log(xml);

And got this:

/Users/dbruhn/repos/testXML/node_modules/xmlbuilder/lib/XMLStringifier.js:149
        throw new Error("Invalid character (" + chr + ") in string: " + str +
              ^
Error: Invalid character (�) in string: test 🐀 here at index 5

Any plans to support emoji? 😄

Of course we support emoji 😄 but you need to set the allowSurrogateChars flag, e.g.:

var xml = builder.create('root', { allowSurrogateChars: true })

Awesome!
