When will direct.yandex begin to understand the Ukrainian language ... or at least letters?

Again a storm of emotions arose in the soul. Negative.
After a rather long break, I sat down for contextual advertising in Yandex.
The idea and the whole system is certainly good, but!
a big minus for me is the lack of knowledge of the Ukrainian language by Yandex!
The fact that the direct does not allow me to use the "word selection" in Ukrainian. language is 10% of the trouble. here you can handle it, although it is already unpleasant.
Since we entered our market, please learn to speak, or at least understand (!) Our language!
But the fact that I can’t add "lions" and other words with the letter "і", "є" in my keywords ... wounded my tender soul very much! not the first time.
Dear representatives of Yandex, teach your child the Ukrainian language.
My colleagues and I will be very grateful!
