Please, when you see something written in Cyrillic, don't assume right away that it's russian. Russian is not the only language that uses Cyrillic. There are also Ukrainian, Belarusian, Bulgarian, Macedonian, Montenegrin, Serbian, Kazakh, Kyrgyz, Tajik, Mongolian.
It's a sensitive topic especially for us Ukrainians because russian language is a weapon. It's a colonial language, it's presented like one and only true slavic language, it erases and replaces other languages. Belarusian is literally on the verge of extinction because of russian. Ukrainian has been banned 134 times throughout history, it is still called a "village language", a dialect of russian. Russian colonialism is literally the reason why there are so many russian speaking people in Ukraine (I was one of them btw). Ukrainian is banned on russian occupied territories and people are getting in trouble or even killed for using it there, Ukrainian POWs in russian captivity are getting brutally beaten for speaking Ukrainian.
Like okay, I can get why there's this confusion, so here's a clue to understand that the language you're looking at definitely is not russian — the letter і. If you see ї (like i but with two dots) it's 100% Ukrainian. If you see j it's Serbian. Russian alphabet also doesn't have such letters as Ђ, Љ, Њ, Ў, Џ (dont confuse with Ц ). Yes, it's not always gonna be easy to detect that the language in front of you is not russian, but when you have trouble with it just ask or run it through any translation app and it'll probably tell you the language.
Hope this will be helpful.
