How to handle special symbols in twig

Question

What I need

I need to show special symbols in view page.

       say name: Sara Fernström oksss.

php code

      {% set  name=value.metadata.name %}

  <h3>

     {%if name|length < 40 %}

{% set strategy = 'html' %}

 {% autoescape 'html' %}
 {{name|escape(strategy)|raw}}
{% endautoescape %}

refrence

http://twig.sensiolabs.org/doc/filters/escape.html

output :

    Sara Fernstru00f6m

but o/p should be:

    Sara Fernström oksss

Have you ever tried to simply output `{{ name }}`? Without all this strategy an escaping thingy? Twig should handle strings properly from the beginning. — Emii Khaos, Feb 07 '15 at 08:05
If you retrieve the value from a database check the correct encoding on that. — Matteo, Feb 07 '15 at 09:37

Hi, i don't understand: if you change the charset, you can print correctly via twig? What problem do you have in the API? PS: if you don't tag me in the comment i will not notify of your comment — Matteo, Feb 13 '15 at 20:55

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());

What's wrong with `UTF-8` that you suggest OP to convert? – zerkms Feb 07 '15 at 08:29
I think in this case it must be like this `{{ data|convert_encoding('YourCharset', 'UTF-8') }}` to get it to work do you agree? – Nickolaus Feb 07 '15 at 08:34

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
