I am writing the sentence correctly and the system says that it's wrong. "Я i мама", right?
I am writing correct sentance but system dont have ukrain language.... R i mama
You use the Latin "i." Cyrillic "і" and Latin "i" are two different characters. That is why your answer is not accepted.
How I write the R the other way around?
You must use the Ukrainian or russian keyboard if you want to do that.
