Ways to avoid encoding Unicode characters in JavaScript programming

When I retrieve data from an API, I receive a STRING like this:

[
  {
    "reason": "Invalid address", 
    "email": "j\u00c3\u00a9r\u00c3\u00b4mel\u00c3\u00a4ufer@com"
  },
  {
    "reason": "Invalid address", 
    "email": "dsfdsf"
  },
]

After parsing the JSON data with JSON.parse(data) and returning it, I noticed strange characters in the frontend rendering of the page like:

email: "jérômeläufer@com"

I want to either escape the \u00c3\u00a9r... characters or encode them, as I need to use these email addresses as parameters for certain actions. However, the weird characters are preventing me from obtaining the correct email.

Is there a way to achieve this?

solution

To address this issue, I am fetching the list of invalid user emails from SendGrid's API using:

GET https://api.sendgrid.com/api/invalidemails.get.json?api_user=user&api_key=key

The returned data looks like this:

[
  {
    "reason": "Invalid address", 
    "email": "j\u00c3\u00a9r\u00c3\u00b4mel\u00c3\u00a4ufer@com"
  },
  {
    "reason": "Invalid address", 
    "email": "dsfdsf"
  },
]

To display the string "j\u00c3\u00a9r\u00c3\u00b4mel\u00c3\u00a4ufer@com" correctly on the web page, I used:

decodeURIComponent(escape(string))

When I needed to remove this email and call the remove email API from SendGrid using:

POST(which is weird,but it's official delete method) https://api.sendgrid.com/api/invalidemails.delete.json

The body of the request is:

body:{
   user: ..,
   key: ...,
   email:unescape(encodeURIComponent(email))
}

This approach worked successfully. Does anyone know why?

Answer №1

JSON.parse is definitely the way to go. The issue lies within the content itself, rather than how it is being processed.

It would be best to communicate with the party responsible for the upstream API to address and rectify the corruption in their data. (Although, if the data originated from you in the first place, there is a possibility that the mistake occurred on your end.)

As a temporary solution, you might be able to correct the corruption post JSON parsing. If the problem involves UTF-8 bytes being misinterpreted as ISO-8859-1, there is a method that can be utilized to perform an encoding/decoding cycle:

>>> decodeURIComponent(escape('jérômeläufer@com'));
'jérômeläufer@com'

(However, if the issue pertains to UTF-8 bytes being mistaken for Windows code page 1252, a simple fix may not be available and the aforementioned method could result in an exception. It's difficult to determine the exact encoding without further information from the faulty string provided above.)

Also, note that jérômeläufer@com does not appear to be a valid email address :-)

Answer №2

It appears that the data is being processed accurately, but the issue lies with the quality of the original data.

To troubleshoot, attempt using online converters to translate character codes like "\u00c3" or "0xC3" into their corresponding characters as decoded by JSON.parse.
