Cyrillic input not recognized in Kotlin Native

You may find attached a screenshot with the simplest Gradle - Kotlin|Native project.
You may easily notice that the English input is being recognized perfectly, while the Cyrillic input gives the blank result. This happens in IDE terminal window and in separate CMD as well. Can anyone explain what’s wrong with Kotlin interpretation of foreign codepages?
Thank you.

PS. The same code compiled for JVM works fine under the condition that codepage in CMD is changed to 1251.
