Question

Is there a way to send JSON using ExpressJS in UTF-8 encoding?

Currently facing an issue with my new web app that I haven't encountered in the past. Experimenting with a simple code snippet like this:

var jsonToSend = {hello: "woørld"};
app.get('/someUrl', function(req, res) {
  res.setHeader('Content-Type', 'application/json');
  res.send(jsonToSend);
}

The output displays as: {"hello":"Woørld"} along with

Content-Type:application/json; charset=utf-8

in the network tab. Attempted using JSON.stringify and adjusting the setHeader charset setting, but still not getting the expected result. How can I ensure the server is encoding the data correctly?

Using WebStorm and already confirmed file encoding is set to UTF-8.

Answer №1

After troubleshooting, it became clear that the root of the problem lay with my IDE. This solution is aimed specifically at WebStorm users:

Upon reviewing, I realized that a project I had initiated on my Windows PC was converting source files to windows-1252 encoding instead of utf-8. To rectify this, navigate to Preferences > File Encoding in WebStorm and ensure that all encoding is set to UTF-8, then convert any old files accordingly. The file encoding information can also be found in the settings view for easy reference.

var jsonData = {"\"greetings"\": "\"earth"\"};
app.get('/specificURL', function(req, res) {
  res.setHeader('Content-Type', 'application/json');
