Summary:                    vtkDataReader and vtkDataWriter don't agree on
signed char
Description: 
vtkDataWriter indicates in the data file that an array is of type "signed char"
by writing out the string "signed_char": 

vtkDataWriter.cxx:1074 
    case VTK_SIGNED_CHAR:
      {
      sprintf (str, format, "signed_char"); *fp << str; 
      signed char *s=
        static_cast<vtkSignedCharArray *>(data)->GetPointer(0);
      vtkWriteDataArray(fp, s, this->FileType, "%hhd ", num, numComp);
      }
    break;

however, vtkDataReader checks for the string "char": 
vtkDataReader.cxx:1446

  else if ( ! strncmp(type, "char", 4) )
    {
    array = vtkCharArray::New();
    array->SetNumberOfComponents(numComp);
  

As a result, a "signed char" data array stored by using vtkDataWriter can not be
read back.
