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: \"Joh         


        

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

ExpressJS version: 4.16.4

Answer 3

My problem solved with this:

res.writeHeader(200 , {"Content-Type" : "text/html; charset=utf-8"});
