How to change the encoding in brackets when processing the form?

Question

PHP

Hello friends, I'm facing a problem.
The fact is that the form handler produces scribbles when encoding UTF-8 in the brackets editor.
After filling out the form in Cyrillic

Here is what the php handler produces

In php code:
<?php
echo $_GET['name'];
?>
Everywhere the encoding is utf-8
In Latin, everything is displayed as it should.

Who can come across this? What could be the problem? :)

Answer 1

<?php

header('Content-Type: text/html; charset=utf-8');

echo $_POST['name'];
