How to remove crocozyabras in bitrex?

Question

1C-Bitrix

I have a website on Bitrex in 1251 encoding. I decided to recode it according to the article dev.1c-bitrix.ru/community/blogs/howto/1466.php
I changed all the settings, but faced with the fact that a lot of files need to be recoded to utf-8 and decided to give up on this matter by changing all the settings in cp-1251. Now, after these changes, I have another problem: when authorizing in the admin panel, all Russian words appear as crocozyabras (such as a complex component), which disappear after a page refresh. The same thing happens with pop-up windows (modules and menus), which are loaded without reloading the page.
Before that, there was no such problem. I checked all the settings several times and they correspond to the original ones.
How to eliminate it?
Because page content cannot be edited.

Answer 1

Putting your krakozyabry into the decoder, you can find out that the character encoding does not match the page encoding.
Composite component -> Composite component
CP1252 → CP1251
You can try to change to 1252 or re-encode again.
Unfortunately, these are just guesses, I hope it will lead to the right thoughts.
