def wide_string(str)
  # if given a nil string, assume caller wants to pass a nil pointer to win32
  return if str.nil?

  # ruby (< 2.1) does not respect multibyte terminators, so it is possible
  # for a string to contain a single trailing null byte, followed by garbage
  # causing buffer overruns.
