Cyrillic InputSimulator does not work, what should I do?

Question

HTML

Hello. In general, when using InputSimulator, Cyrillic does not work, instead of Russian characters, '?????? ??? ??', at the same time when everything works stably in English. Who faced similar, did not find a solution? Already, by the way, I came across a similar question on the toaster, but I did not find sound answers. help mi lee
