Phalcon 3.0 json utf8 render

Hello, After I have updated Phalcon from 2.0.10 to Phalcon 3.0 (with PHP 7.0.9) my endpoints dosent support utf8 chars (special Sweedish characters) when rendering :

{"status":"success","http_code":200,"data":[{"id":1,"name":"SOME NAME","slug":"some-name"},{"id":2,"name":"SOME & NA\u00c4DG\u00c5ME","slug":"some-name"},{"id":3,"name":"SOME & NAME","slug":"some-name"} ...

Codes like : \u00c4DG\u00c5 , \u00c4 ... So im getting an errorors at enpoints that retrives data with json ..

#1 [internal function]: Phalcon\Mvc\View-&gt;render('cars', 'brends', Array)<br />
#2 /var/www/project-core/public/index.php(67): Phalcon\Mvc\Application-&gt;handle()<br />
#3 /var/www/project-core/public/index.php(73): Application-&gt;main()<br />
#4 {main}

Any1 have problems like this?

Aditional info: When I vardump() my query results from db, characters are well writen with UTF8 (same line in my DB with Sweedish special characters). So problem is encoding it json. Im using Fractal Transformers
