Dynamics NAV 2016 Unicode in Dev Env

Hi to all

Can anyone have the problem with the not supported Unicode in Dynamics NAV 16 and is there any way to fix this huge problem in Dynamics NAV 16. I have a problem with inserting the translation in Dev Env for 1251 (MKI) language. When I add translation for new od existing labels in Dev Env (ENU=Test;MKI=MyLanguage Test) all i see in RTC are characters ...
How is it possible when older versions support this, from the newest version to be excluded such helpful part

I think this is HUGE problem with Dev Env, so if someone have idea or solve this problem please let me know

Best Regards
