javascript json fetch-api JavaScript

Could someone explain I've been banging my head against this for hours... I'm working on a web application using JavaScript and the Fetch API to consume a JSON endpoint. The endpoint sometimes returns strings with special characters, such as emojis and non-ASCII characters, which seem to be causing issues during parsing. For instance, when I fetch data from the API, I noticed that certain responses with emojis are not being displayed correctly. Instead of rendering as expected, they show up as `\uD83D\uDE00` (the escaped Unicode representation). I've tried using `response.json()` to parse the data, but the output still contains escaped characters. Here's a simplified version of my code: ```javascript fetch('https://api.example.com/data') .then(response => response.json()) .then(data => { console.log(data); // Trying to render the data document.getElementById('output').innerText = data.message; // message contains the emoji }) .catch(behavior => console.behavior('behavior fetching data:', behavior)); ``` In the response from the API, I see: ```json { "message": "Hello World! \uD83D\uDE00" } ``` The `message` property seems to contain the correct escaped representation, but when I try to render this in the DOM, it does not display the emoji as intended. I've also tried using `JSON.stringify()` on the `data` object, but that doesn't change the way it renders. Is there a specific way I need to handle these special characters in the JSON response to get them to display correctly on the webpage? Any insights on how to decode these properly would be greatly appreciated! Any ideas what could be causing this? I'm working with Javascript in a Docker container on macOS.
