My Solution

With the help of a non vagrant-related StackOverflow solution, I solved the issue by changing the line 32 in "Vagrantembeddedgemsgemsvagrant-2.0.1libvagrantutil" as:

data << io.readpartial(READ_CHUNK_SIZE).encode('UTF-8', invalid: :replace, undef: :replace, replace: '?')

即修改源代码，说改就改：

  #data << io.readpartial(READ_CHUNK_SIZE).encode("UTF-8", Encoding.default_external)
  data << io.readpartial(READ_CHUNK_SIZE).encode('UTF-8', invalid: :replace, undef: :replace, replace: '?')

  修改之后，重新执行命令vagrant up
