How to stop PrestaShop from translating diacritical characters in HTML entities?

Question

PHP

I am making a Czech online store. In Czech, we have letters with diacritics (superscripts) like Š (Ш), Ž (Ж), Č (Ч), Ý (solid long and, analogous to the Russian "ij" at the end of adjectives), etc. So when I enter these letters in CMS PrestaShop articles, save, and then open the corresponding article, in the code (and I prefer to edit the code, not WYSIWYG), all these letters are replaced with the corresponding HTML entities. For example Š on scaron, Ý on yacute etc. As a result, the source code becomes completely unreadable, it becomes impossible to search for it, and letters instead of a couple of bytes (how many Latin characters with diacritics take in UTF8) begin to occupy all eight.
The fact that only those characters for which the corresponding HTML entities are defined are subjected to transformation, while the rest remain untouched and are saved and displayed without problems, as if hinting at the fact that all this is not necessary at all.
Accordingly, the question is how to get rid of this feature and whether there are any arguments in favor of leaving it.
Raised a question on the official PrestaShop forum , but did not meet with understanding. Maybe someone here can advise.
Thanks in advance.

Answer 1

The answer was found (answered on the official forum): you need to edit /js/tinymce.inc.js, adding entity_encoding : "raw" to the default_config, something like this:

// safari,pagebreak,style,table,advimage,advlink,inlinepopups,media,contextmenu,paste,fullscreen,xhtmlxtras,preview
  default_config = {
    entity_encoding : "raw", // <- добавляем вот эту строчку сюда
    selector: ".rte" ,
