This is specific to custom keyboard layouts, even if I generate them from system ones provided by Apple. When using Russian system layout - Cyrillic letters are displayed correctly.
Also if I copy Russian text from outside of wine and paste it into text field - this also works fine. So, looks like the issue is related to input and custom keyboard layouts specifically.
Yeah. That's weird.
Can you share which command line, environment variables or config settings can I use to gather logs you are asking for?
