The encoding of the plugin has gone wrong, what should I do?

Question

1C-Bitrix

Foreign hieroglyphs crawl out in the control panel, instead of Russian letters, on the plate that attached it all, you can see the "screenshot"
Apparently the site has an encoding of 1251 windows
The plugin has utf-8
The plugin was introduced into the site by roundabout paths and paths, not through the marketplayZ, but copied from another site, which brotherly borrowed a copy. And here are the ancient manuscripts on which the plug-in was introduced https://libramedia.ru/1s-bitriks-ustanovka-modulej...

Answer 1

Akhtungs are usually called certain people, so punctuation rules!
Any plugin can be recoded for example in notepad++

Answer 2

In this module, in the bitrix/modules folder, there should be a file with lang - open it and change the hieroglyphs.
