Bash script for searching Russian words?

Question

bash

Good afternoon!
There is a php script with this content

<?php
echo 'Привет'. $testvar . 'мир!';
?>

It is necessary to find the Russian text in quotes in all php files and replace it with a random variable, utf-8 encoding of php scripts. All this must be done with a bash script. Those. should get the following

<?php
echo $kasjdks. $testvar . $asdllk;
?>

and in file 1.txt
$kasjdks= 'Hi';
$asdlk = 'world!';
And there are also php files, just with html, i.e.

<?php
<BR>Пример Мир!<BR>
<a>Тест</a>
?>

Here, too, it is necessary to organize a search and replace the Russian text. All this idiocy is needed to implement the site’s multilingualism, before me the site was made by other people, and all the Russian text was shoved directly into scripts, it’s
not a bunch of scripts to change everything by hand, so I came up with such an idea, I can’t compose a competent regular program, help, please, or maybe someone has already encountered such a situation, maybe there are other solutions, thanks in advance!

In general, they make the _() function and write all phrases in English like _("hello"). And this function itself already goes where it needs to and takes the phrase in the correct language in accordance with the locale. Thus, the program is translated into any language by editing such files with pairs (English, Chinese).
