What is the most correct MIME for a response with JSON?

Question:

For a while, I've been sending back JSON responses as plain text: plain/text , however I'd like to finally be able to send the correct Content-Type header.

Here are some of the suggested "standards" for JSON MIME:

application/json
application/x-javascript
text/javascript
text/x-javascript
text/x-json

However, which one is the correct one, or just the best one regarding security/customer support (browsers, etc.)?

^{Translation of the question "What is the correct JSON content type?"}

Answer:

For JSON :

According to the IANA registration and RFC 4627 : application/json encoded in UTF-8 .

For JSONP :

application/javascript is also in UTF-8 .

When JSON creator Douglas Crawford was asked why not text/json , he replied that it's not a JS script, but it's not text either, so application/* rather than text/* .
