  17471. * CharStrings are encoded following the the CharString Encoding sequence

  17473. * The value in a byte indicates a command, a number, or subsequent bytes
  17474. * that are to be interpreted in a special way.
  17475. *
  17476. * CharString Number Encoding:
  17477. * A CharString byte containing the values from 32 through 255 inclusive
  17478. * indicate an integer. These values are decoded in four ranges.
  17479. *
  17480. * 1. A CharString byte containing a value, v, between 32 and 246 inclusive,
  17481. * indicate the integer v - 139. Thus, the integer values from -107 through
  17482. * 107 inclusive may be encoded in single byte.
  17483. *
  17484. * 2. A CharString byte containing a value, v, between 247 and 250 inclusive,
  17485. * indicates an integer involving the next byte, w, according to the formula:
  17486. * [(v - 247) x 256] + w + 108
  17487. *
  17488. * 3. A CharString byte containing a value, v, between 251 and 254 inclusive,
  17489. * indicates an integer involving the next byte, w, according to the formula:
  17490. * -[(v - 251) * 256] - w - 108
  17491. *
  17492. * 4. A CharString containing the value 255 indicates that the next 4 bytes
  17493. * are a two complement signed integer. The first of these bytes contains the
  17494. * highest order bits, the second byte contains the next higher order bits
  17495. * and the fourth byte contain the lowest order bits.
  17496. *
  17497. *
  17498. * CharString Command Encoding:
  17499. * CharStrings commands are encoded in 1 or 2 bytes.
  17500. *
  17501. * Single byte commands are encoded in 1 byte that contains a value between
  17502. * 0 and 31 inclusive.
  17503. * If a command byte contains the value 12, then the value in the next byte
  17504. * indicates a command. This "escape" mechanism allows many extra commands
  17505. * to be encoded and this encoding technique helps to minimize the length of
  17506. * the charStrings.
