PHP UTF-8编码回应问号

Question

I'm trying to echo a json_response with unicode characters using the following code:

function utf8ize($d) {
if (is_array($d)) {
    foreach ($d as $k => $v) {
        $d[$k] = utf8ize($v);
    }
} else if (is_string ($d)) {
    return utf8_encode($d);
}
return $d;
}

used like this:

echo json_encode(utf8ize($response));

The problem with this is that some characters are encoded properly and other characters like ć and ś are sent as question marks as seen in the below image:

I'm not sure how to fix this.

Answer 1

You could try to execute

SET NAMES utf8

As a query. After you've made the connection.

Then just in case set this header

header('Content-type: text/plain; charset=utf-8');

Then try again
