That's all extended latin, though, right? And the accents are visible.
Not like having 'е' and 'і' instead of 'e' and 'i'.
Or even 'г' instead of 'r', though you can technically see that one.
Thing is, Cyrillic and Greek character sets are generally used independently, which is why they have confusable characters in the first place. It's pretty rare to have a legit need to mix Cyrillic or Greek characters in with Latin.
