Create directory with UTF-8 name in Vim
What I usually do is I switch to the explorer mode with :Explore and press d. It asks me for the directory name, then.
:h :Explore:h netrw-d
try this
:!mkdir "привет"
Found it.
I should use iconv function:
:call mkdir(iconv("привет", "utf-8", "cp1251"))
You can change encod. Add:
chcp 65001
:call mkdir("привет")
chcp 65001 - UTF-8
