Sure there is a common application in Math/Algebra and Physics (if the person reading the sign even bothered to learn and didn't forgot everything the second they stepped out) and in product/brand names in the everyday life, but there is a difference between knowing the alphabet and having a vague idea how some letters are pronounced.
Also there is enough of false friends (like `B` or `P`) to completely jumble the pronunciation and consequently fail the understanding.
Russia has an almost mandatory foreign language in their education[0], which is a subject to availability I suppose - if there is no one who can teach the language in some remote village then nothing can be done, though with all that COVID measures I suppose the idea of remote learning is there.
But again, it all depends on the quality of education, the abilities and the will of the student and not being forgotten. People who don't use another language would almost completely lose it in 3-7 years even if they had A+ for it in the school.
Though it all more applies to an older generations, I think, because younger ones should be explicitly exposed to the Latin alphabet through the keyboards of their computers and smartphones, in Instagra/TikTok handles, email addresses and so on.
