我得到“？”使用ejs模板引擎渲染view.ejs时出现字符错误。这是nodejs中的源代码：
const express = require('express');
const path = require('path');
//initial app
const app = express();
app.use(express.static(path.join(__dirname,'/public')));
//Load view engine
app.set('views',path.join(__dirname,'views'));
app.set('view engine', 'ejs');
app.get('/', function(req,res){
res.render('index'); });
app.listen(3000, function(){
console.log("server started on port 3000...");});
例如“LêBảoCường”将变成L？ B？o C ?? ng。这是index.ejs的内容

</html>我错误地将我的index.ejs文件保存为shift_jis编码。用utf8编码保存该文件可以解决我的问题。
