Instead of the Russian language, incomprehensible characters

We are talking about version 1.14.41 ( I didn 't find where to choose !)

Russian keyboard layout is visible in the chat, but when you click on the letters in the line, it writes incomprehensible characters and numbers. moreover, the suggestions of words in a russian output correctly, but using them we get incomprehensible words in the chat line.

Before that, we connected a keyboard and mouse to the PS4 console via bluetooth and noticed just after that.
