How to decode characters like "\\u00e2" or "\\u00ea" to unicode characters?

Question

I'm using ASP.NET Core and I'm trying to get Twitter's user profile. The server returned a response text like this:

"{\"id\":3278814606,\"id_str\":\"3278814606\",\"name\":\"T\u00e2n Nguy\u00ea\u0303n\",\"screen_name\":\"_ntnguyen\",\"location\":\"\",\"description\":\"\",\"url\":null,\"entities\":{\"description\":{\"urls\":[]}},\"protected\":false,\"followers_count\":1,\"friends_count\":39,\"listed_count\":0,\"created_at\":\"Mon Jul 13 20:32:53 +0000 2015\",\"favourites_count\":0,\"utc_offset\":null,\"time_zone\":null,\"geo_enabled\":false,\"verified\":false,\"statuses_count\":0,\"lang\":\"en\",\"contributors_enabled\":false,\"is_translator\":false,\"is_translation_enabled\":false,\"profile_background_color\":\"C0DEED\",\"profile_background_image_url\":\"http:\/\/abs.twimg.com\/images\/themes\/theme1\/bg.png\",\"profile_background_image_url_https\":\"https:\/\/abs.twimg.com\/images\/themes\/theme1\/bg.png\",\"profile_background_tile\":false,\"profile_image_url\":\"http:\/\/pbs.twimg.com\/profile_images\/1058043873358827521\/YOOYwQY5_normal.jpg\",\"profile_image_url_https\":\"https:\/\/pbs.twimg.com\/profile_images\/1058043873358827521\/YOOYwQY5_normal.jpg\",\"profile_banner_url\":\"https:\/\/pbs.twimg.com\/profile_banners\/3278814606\/1438769550\",\"profile_link_color\":\"1DA1F2\",\"profile_sidebar_border_color\":\"C0DEED\",\"profile_sidebar_fill_color\":\"DDEEF6\",\"profile_text_color\":\"333333\",\"profile_use_background_image\":true,\"has_extended_profile\":false,\"default_profile\":true,\"default_profile_image\":false,\"following\":false,\"follow_request_sent\":false,\"notifications\":false,\"translator_type\":\"none\",\"suspended\":false,\"needs_phone_verification\":false}"

The user name is in the property:

{
    name: "T\\u00e2n Nguy\\u00ea\\u0303n"
}

How can I decode the string to the unicode character (Tân Nguyễn)?

I've tried:

console.log(decodeURIComponent("T\\u00e2n Nguy\\u00ea\\u0303n"));

but it loged with the same string.

The problem is you're escaping the Unicode formatting with the \\ at the start. Changing the values to, for example, \u00e2n, would output the correct â:

console.log(decodeURIComponent("T\u00e2n Nguy\u00ea\u0303n"));

You could also use JSON.parse(), as per this answer.

Both of these methods will output the following:

`decodeURIComponent` has nothing to do here, nor JSON.parse, `console.log("T\u00e2n Nguy\u00ea\u0303n")` will output `"Tân Nguyễn"` – Kaiido Mar 08 '19 at 01:31

var stringifyData = "{\"id\":3278814606,\"id_str\":\"3278814606\",\"name\":\"T\u00e2n Nguy\u00ea\u0303n\",\"screen_name\":\"_ntnguyen\",\"location\":\"\",\"description\":\"\",\"url\":null,\"entities\":{\"description\":{\"urls\":[]}},\"protected\":false,\"followers_count\":1,\"friends_count\":39,\"listed_count\":0,\"created_at\":\"Mon Jul 13 20:32:53 +0000 2015\",\"favourites_count\":0,\"utc_offset\":null,\"time_zone\":null,\"geo_enabled\":false,\"verified\":false,\"statuses_count\":0,\"lang\":\"en\",\"contributors_enabled\":false,\"is_translator\":false,\"is_translation_enabled\":false,\"profile_background_color\":\"C0DEED\",\"profile_background_image_url\":\"http:\/\/abs.twimg.com\/images\/themes\/theme1\/bg.png\",\"profile_background_image_url_https\":\"https:\/\/abs.twimg.com\/images\/themes\/theme1\/bg.png\",\"profile_background_tile\":false,\"profile_image_url\":\"http:\/\/pbs.twimg.com\/profile_images\/1058043873358827521\/YOOYwQY5_normal.jpg\",\"profile_image_url_https\":\"https:\/\/pbs.twimg.com\/profile_images\/1058043873358827521\/YOOYwQY5_normal.jpg\",\"profile_banner_url\":\"https:\/\/pbs.twimg.com\/profile_banners\/3278814606\/1438769550\",\"profile_link_color\":\"1DA1F2\",\"profile_sidebar_border_color\":\"C0DEED\",\"profile_sidebar_fill_color\":\"DDEEF6\",\"profile_text_color\":\"333333\",\"profile_use_background_image\":true,\"has_extended_profile\":false,\"default_profile\":true,\"default_profile_image\":false,\"following\":false,\"follow_request_sent\":false,\"notifications\":false,\"translator_type\":\"none\",\"suspended\":false,\"needs_phone_verification\":false}";

var parseData = JSON.parse(decodeURIComponent(stringifyData));

console.log(parseData.name);
