php and python encoding?

Question

PHP

Hello everyone, the bottom line is, there is a script written in php that sends a variable to the python script, the python processes and returns the changed string.
PHP:

$search = $_POST["search"];
$search = shell_exec('hh.py ' . $search);
print($search);

Python:

import sys
import pymorphy2
result = "дерево" 
print (result)

As a result, the output is question marks .... the fact is that both files are encoded in utf-8 without BOM, while I added the #!/usr/bin/env pythons header to the python in the IDE, it shows all the rules, the Russian string .. .but in php it returns question marks....
Are there any options how to fix it?

Answer 1

At the beginning of the script, write
In the script code
result = u"дерево"
