Reproduction Link

https://vue-hn.now.sh/top

Steps to reproduce

open in IE9 browser

What is Expected?

it('basic-rendering-entities-encoding', function(done){
    var renderer = require('vue-server-renderer').createRenderer()

    var Vue = require('vue')
    var app = new Vue({
      template: '<div id="app">汉字 {{chineseDataMsg}} {{testEntity}}</div>',
      data: function(){
        return {
          chineseDataMsg: '测试',
          testEntity: '<script>alert(1);</script>'
        }
      }
    })

    renderer.renderToString(app, function(err, html){
      try{
        html.should.equal('<div id="app" server-rendered="true">汉字 测试 &lt;script&gt;alert(1);&lt;/script&gt;</div>')
      } catch(e){
        done(e)

    })
  })

What is actually happening?

some entities codes can not be rendered by IE9, the page contains some entities codes like :

I changed some codes as following and it works in IE9.

// write(node.raw ? node.text : entities.encodeHTML(String(node.text)), next)
 write(node.raw ? node.text : require('html-entities').AllHtmlEntities.encode(String(node.text)), next)

Are there some problems if we only encodes HTML Entities ( not encode chinese and some special characters ) ?
