How to get UTF-8 in Node.js?

Question

How do I get UTF-8 support on my API? At the moment, a string outputs like this:

name: "John D�m" 

Instead of:

name: "John Döm" 

Checkout app.js below:

var express = require('express'),     driver = require('./driver');  var app = express();  app.configure(function () {     app.use(express.logger('dev'));     app.use(express.bodyParser()); });  app.get('/drivers', driver.findAll);  app.listen(3000); console.log('Up: http://127.0.0.1:3000/'); 

Answer 1

Hook into you response generator or create a middleware that does the following:

res.header("Content-Type", "application/json; charset=utf-8"); 

Otherwise the browser displays the content in his favorite encoding.

If this doesn't help you DB is probably in the wrong encoding.

Edit: Since the answer is nearly 5 years old, the API has changed. For current node.js versions use:

res.setHeader("Content-Type", "application/json; charset=utf-8"); 

Answer 2

I can't solve this problem with setting content type. I solved this problem with encode function.

res.cookie('someCookie', someCookie, {   encode: c => c, }); 

For more information: express cookie
