Vagrant doesn't understand Cyrillic?

Question

virtual box

Launched vagrant. I create a file with the name "icon.png". I connect to vagrant via vagrant ssh and see "?????????????.png"

vagrantFile:

config.vm.box = "ubuntu/trusty64"
  config.vm.box_check_update = false
  config.vm.hostname = "firstV"  

  config.vm.provider "virtualbox" do |vb|
     vb.gui = false
     vb.memory = 2048
  end

   config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"
  config.vm.synced_folder "project", "/var/www/project"
