 *  Y : 2-byte int16
 *  I : 4-byte int32
 *  F : 4-byte float
 *  D : 8-byte double
 *  L : 8-byte int64
 *  i : array of int32
 *  f : array of float
 *  d : array of double
 *  l : array of int64
 *  b : array of 1-byte booleans (0x00 or 0x01)
 *  S : string (array of 1-byte char)
 *  R : raw data (array of bytes)
