Malformed UTF-8 Characters in JSON Encoding

When using json_encode() to encode data arrays containing Russian characters, you may encounter an error related to malformed UTF-8 characters. This issue can arise if the data contains non-UTF-8 characters, even if the majority of the characters are UTF-8 encoded.

Solution:

To resolve this issue, employ the mb_convert_encoding() function on the data field containing Russian characters. This function will remove any non-UTF-8 characters, ensuring that the data is properly encoded in UTF-8.

<code class="php">$data['name'] = mb_convert_encoding($data['name'], 'UTF-8', 'UTF-8');</code>

By applying the above code, you can effectively remove non-UTF-8 characters and ensure that the data is correctly encoded for use with json_encode().
