javascript - Wrong charset with JSON data in Node.js project -

how can fix following problem?

if use code on app.js renders page no problem:

app.get('/layout', function(req, res){     res.render('empreendimentolayout', {"titulo": "página layout"}) })

.ejs file this:

<head> <title><%=titulo%></title> </head>

but if on app.js:

var routes = require('./routes'); app.get('/layout', routes.layout);

and inside layout.js:

exports.layout = function(req, res){ res.render('empreendimentolayout', {"titulo": "página layout"}) })

then rendering like: p�gina layout

it happens in json data send. if coming directly app.js works well, if coming .js file comes wrong charset.
