Latin C and Cyrillic С aren't the same letter. The latter is actually an "s". It would be a pain in the ass to work with strings if those Cyrillic letters that look like their Latin counterparts reused their codepoints. Imagine having to convert "M" to lowercase. Would that return "m" or "м"? Same for "H", "h" or "н"?

And, actually, there was some really really cursed Soviet encoding that did this to save bits. The Russian railway company still uses it[1] to this day.

Well, as a moderately old Czech, I'm somewhat familiar with Cyrillic. They kind of used to force it on us in schools.
