Answer 1

Check how you store the data in your database with the charset and collate params as example:

namespace Acme\DemoBundle\Entity;

use Doctrine\ORM\Mapping as ORM;


/**
 * @ORM\Entity(repositoryClass="MyEntityRepository")
 * @ORM\Table(name="my_entity",
 *      options={"collate"="utf8mb4_unicode_ci", "charset"="utf8mb4"})})
 */
class MyEntity
{
  ....

Hope this help

Your issue is not with Twig, your issue is with your page and string encoding.

Make sure the string is UTF-8 before it is passed to Twig. Make sure the document is UTF-8.

Then use

{{ data }}

to output your string.

I work with åöä all the time(swedish) and literally never had to use anything else.

You will need to decode the string in the proper charset:

{{ data|convert_encoding('UTF-8', 'YourCharset') }}

data will be your string, the first value is the output-charset the second the input-charset, you can also see the twig doc for this: http://twig.sensiolabs.org/doc/filters/convert_encoding.html

If the this doesn't work maybe try to decode the variable inside your php code:
For your code it would be something like this I think:

value.metadata.setName(utf8_decode(value.metadata.getName());
