php json utf8 php8.2 PHP

I'm confused about I'm working on a project and hit a roadblock. I'm working with an scenario while trying to encode an array into JSON format using `json_encode` in PHP 8.2. The array contains a mix of English and non-ASCII characters (specifically, Cyrillic characters). When I call `json_encode`, it seems to corrupt the UTF-8 encoding of the Cyrillic characters, resulting in unexpected output like `Писмо` instead of `писмо`. Here's the code I'm using: ```php $data = [ 'message' => 'Hello', 'cyrillic' => 'писмо', ]; $json = json_encode($data); if ($json === false) { echo 'JSON behavior: ' . json_last_error_msg(); } else { echo $json; } ``` I've tried ensuring that the input data is properly encoded in UTF-8, and I've even used `mb_convert_encoding` before calling `json_encode`, but the result is still the same. The `json_last_error_msg()` returns no errors, and the output for English characters works perfectly, but I need to make sure the Cyrillic characters are correctly represented in the JSON. Is there a specific setting or approach I should be using in PHP 8.2 to handle this correctly? Any insights would be appreciated! My development environment is Windows. This is part of a larger REST API I'm building. Cheers for any assistance!
