The problem with Cyrillic in r.keyboard()

[debugger1979]

Hello!
I found a problem with the output of Cyrillic characters in r.keyboard(). When trying to perform an operation, the script freezes. I have already seen a similar topic that described problems with Chinese characters. I tried the option of adding a UTF-8 string to the body of the script, but nothing worked. I used the option with r.clipboard() - the issue was resolved, but partially. I need to perform a text "typing" operation in a text editor. It is typing, not pasting from the clipboard
Tell me, please, is it possible to solve this problem?
