How to catch "non-Latin" characters in android?

Question

Java

It is necessary to catch all pressing on the keyboard of the device. I show it programmatically with

...
      if (view != null) {
            InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.showSoftInput(view, 0);
        }
...

I put the handler

.....
        view.setOnKeyListener(new View.OnKeyListener() {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                int keyunicode = event.getUnicodeChar(event.getMetaState() );
                char character = (char) keyunicode;
                Log.i("KEYBOARD",  character);
                ......
                return true;
            }
        });

Latin letters, numbers, etc. are intercepted, but when I switch to the Russian keyboard, the event is not even called, I suspect that this will also be the case in other languages. How to make it intercept everything from the keyboard?
Thanks
