Debian Stable php-5.4上的Symfony2 JsonResponse utf8编码问题

Question

当我返回UTF8字符时,我在Debian Stable php5(5.4.39-0 + deb7u1)上遇到JsonResponse问题.

我在Debian Testing php5(5.6.6 + dfsg-2)上开发了一个应用程序,下面的代码就像一个魅力:

$response = new JsonResponse();
$response->headers->set('Content-Type', 'application/json');
$response->setData($data);
return $response;

但是在部署到稳定的prod服务器之后,我开始为完全相同的DB/Data字符集等获得以下异常:

request.CRITICAL: Uncaught PHP Exception InvalidArgumentException: "Malformed UTF-8 characters, 
possibly incorrectly encoded." at /site/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/JsonResponse.php
 line 123 {"exception":"[object] (InvalidArgumentException(code: 0): 
Malformed UTF-8 characters, possibly incorrectly encoded. at 
/site/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/JsonResponse.php:123)"} []

作为$ data DO传递的DB的响应包含我无法控制的UTF8字符.我只需要显示它们.

我想我遇到了5.4的bug,但是我怎么能轻松地走动呢？我试过了:

    $response = new JsonResponse();
    $response->headers->set('Content-Type', 'application/json');
    $response->setEncodingOptions(JSON_UNESCAPED_UNICODE);
    $response->setData($data);
    return $response;

但我得到了同样的错误.

想法？

在讨论#symfony频道后,我发现了一个解决方法:

    $response = new Response(json_encode($data, JSON_UNESCAPED_UNICODE));
    $response->headers->set('Content-Type', 'application/json');
    return $response;

欢迎其他好的解决方案.我认为这个解决方案是一个肮脏的黑客......
