JSON file from facebook, how to display russian text?

Question

JavaScript

I exported a file with posts from the FB community in JSON format. Instead of displaying Russian texts there
\u00d0\u00a4\u00d0\u00be\u00d1\u0082\u00d0\u00be \u00d0\u00b8\u00d0\u00b7 \u00d1\u0085\u00d1\u0080\u00d0\u00be\u00d0\u00bd\u000b u00d0\u00ba\u00d0\u00b8.
On stackoverflow , I found a way to convert to readable data using PHP:

$json = changeCharset(json_decode($str, TRUE));

var_dump($json);

function changeCharset( $array ){
    array_walk_recursive( $array, function(&$item) { 
       $item = iconv("UTF-8", "ISO-8859-1", $item); 
    });
    return $array;
}

I can't understand why we are converting from UTF-8 to ISO-8859-1, and how can I convert the json file so that it can be viewed by a standard editor without resorting to converting using a PHP function.

Answer 1

Try to use the JSON_UNESCAPED_UNICODE parameter when you get your json file
Here is the whole line:
$json = json_encode($return_info, JSON_UNESCAPED_UNICODE);
I used to have this problem myself. Decided just like that.

Answer 2

$json = utf8_encode($str); 
$results = json_decode($json, TRUE);
var_dump($json);

OR as mentioned above

$json = json_decode(json_encode($str, JSON_UNESCAPED_UNICODE), TRUE);
var_dump($json);

As of PHP 7.2.0, the utf8_encode function has been moved to PHP core, thus removing the requirement for an XML extension to use this function.
