When I yank russian characters, say тест, to system clipboard ("+y) and then paste it in a shell or a browser I get this —Ç–µ—Å—Ç. How to fix this?
Vim
:set encoding?
encoding=utf-8
:set fileencoding
fileencoding=utf-8
Shell
echo $LC_CTYPE
UTF-8
I had the same issue and fixed it by adding lang en_US.UTF-8 to my ~/.config/nvim/init.vim (using Neovim). You could try adding that to your ~/.vimrc.

Setting correct locale for a shell with these lines added to .zshenv solves the issue.
set -a
LC_CTYPE=en_US.UTF-8
LC_ALL=en_US.UTF-8
set +a
