Can not use a multi-byte character set for data binding

[Tanoemon]

var base = new Vue({
    el: '#base',
    template: html,
    data: {
      漢字: {
        太郎君: '1000',
        花子: '4000'
      }
    }
});

<div>{{漢字.太郎君}}</div>
<div>{{漢字.花子}}</div>

Result in Chrome

[Vue warn]: Error when evaluating expression "漢字.太郎君".
debug.js:33 ReferenceError: 漢字 is not defined
[Vue warn]: Error when evaluating expression "漢字.花子".
debug.js:33 ReferenceError: 漢字 is not defined

Unfortunately, Vue's expression parser only support alphanumeric identifiers. Avoid using unicode chars as identifiers.
