Hi,

How about some modification of create_function method like this:
  def self.create_junction(to, from,unicode=false)      # Normalize the paths      to.tr!('/', "\\")      from.tr!('/', "\\")
      to_path    = 0.chr * 260      from_path  = 0.chr * 260      buf_target = 0.chr * 260
      if GetFullPathName(from, from_path.size, from_path, 0) == 0         raise StandardError, 'GetFullPathName() failed: ' + get_last_error      endif unicode      if GetFullPathNameW(to, to_path.size, to_path, 0) == 0         raise StandardError, 'GetFullPathName() failed: ' + get_last_error      endelse      if GetFullPathName(to, to_path.size, to_path, 0) == 0         raise StandardError, 'GetFullPathName() failed: ' + get_last_error      endend      to_path   = to_path.split("\0\0").first      from_path = from_path.split(0.chr).first
      # You can create a junction to a directory that already exists, so      # long as it's empty.
if unicode      rv = CreateDirectoryW(to_path, 0)      if rv == 0 && rv != ERROR_ALREADY_EXISTS         raise StandardError, 'CreateDirectory() failed: ' + get_last_error      end
      handle = CreateFileW(         to_path,         GENERIC_READ | GENERIC_WRITE,         0,         0,         OPEN_EXISTING,         FILE_FLAG_OPEN_REPARSE_POINT | FILE_FLAG_BACKUP_SEMANTICS,         0      )else      rv = CreateDirectory(to_path, 0)      if rv == 0 && rv != ERROR_ALREADY_EXISTS         raise StandardError, 'CreateDirectory() failed: ' + get_last_error      end
      handle = CreateFile(         to_path,         GENERIC_READ | GENERIC_WRITE,         0,         0,         OPEN_EXISTING,         FILE_FLAG_OPEN_REPARSE_POINT | FILE_FLAG_BACKUP_SEMANTICS,         0      )end...end
And call like this:from = "C:\\test"Dir.mkdir(from) unless File.exists?(from)#unicode folder nameto = "\x95\x03\xBB\x03\xBB\x03\xAC\x03\xC3\x03\0\0"  #  "Ελλάσ"Dir.create_junction(to, from,true)#ansi folder nameto = "ansi"Dir.create_junction(to, from,false)
