For whom does ZF2 work incorrectly with the Russian language?

Question

Zend Framework

ZF2.3.3. Doctrine gets the correct data from the database, but in the view of the form the line "echo $this->formRow($form->get('mark'));" gives inputs in the value field instead of Russian - Korean characters. The encodings of the base, tables and strings are all utf8, in the $form object everything is also in Russian.
Also when forming the form
$this->add(array(
'name' => 'submit',
'type' => 'Submit',
'attributes' => array(
'class' => 'btn btn-success',
'value' => 'Add',
'id' => 'submitbutton',
),
));
value will be hieroglyphs. It looks like some kind of handler, like htmlentities().

Answer 1

What is the page encoding? Zend\Form\View\Helper\AbstractHelper - escaping happens here in the createAttributesString() method

Answer 2

zf2 automatically applies escaping in the form to all attributes
with Cyrillic in general, the trouble turns out, you can’t even spell the placeholder properly, I
