Send a JSON response in UTF-16 encoding in express server

Question

I have a client which is reading the response from my server in UTF-16, so my normal JSON appears to be something written in chinese like this

but response is something like this:

{
    "success": true,

    "user": {
        "profile": {
            "fullName": "Ankit"
        },
        "initialSetup": false,
        "role": "USER",
        "verified": true,
        "active": true,
        "_id": "5cfbcbb46d623c2d8be2cb17",
        "email": "abc@xyz.com",
        "organization": "ABC",
        "createdAt": "2019-06-08T14:52:36.849Z",
        "updatedAt": "2019-07-29T07:14:58.130Z",
        "__v": 0,
        "organizationId": "5cfbcbb56d623c2d8be2cb18"
    }
}

I want to know if there is a way I can send the response, so the client can also read it as JSON above, and not as chinese characters.

Answer 1

Make sure that your server sends the correct HTTP header for json data ( Content-type: application/json ) and encodes the data either as utf-8, which is the default encoding for this content type, or sends an Encoding: header that contains the character encoding used.

If the client is unable to interpret this correctly, it's their fault. You can't seriously be expected to work around faulty client implementations at the server side.
