Ideally, the encoding is usedUTF-8.

If you want to save a file in UTF-8 with comments, but without rewriting them:
You can restore the encoding Windows-1251, select all, cut, change the encoding to UTF-8 , and paste the cut. This way you will have a file in the format UTF-8 and the comments will be saved in Cyrillic.

For decoding, you can use this service.
