 +   * The value in a byte indicates a command, a number, or subsequent bytes

 +   *
 +   * CharString Number Encoding:
 +   *  A CharString byte containing the values from 32 through 255 inclusive
 +   *  indicate an integer. These values are decoded in four ranges.
 +   *
 +   * 1. A CharString byte containing a value, v, between 32 and 246 inclusive,
 +   * indicate the integer v - 139. Thus, the integer values from -107 through
 +   * 107 inclusive may be encoded in single byte.
 +   *
 +   * 2. A CharString byte containing a value, v, between 247 and 250 inclusive,
 +   * indicates an integer involving the next byte, w, according to the formula:
 +   * [(v - 247) x 256] + w + 108
 +   *
 +   * 3. A CharString byte containing a value, v, between 251 and 254 inclusive,
 +   * indicates an integer involving the next byte, w, according to the formula:
 +   * -[(v - 251) * 256] - w - 108
 +   *
 +   * 4. A CharString containing the value 255 indicates that the next 4 bytes
 +   * are a two complement signed integer. The first of these bytes contains the
 +   * highest order bits, the second byte contains the next higher order bits
 +   * and the fourth byte contain the lowest order bits.
 +   *
 +   *
 +   * CharString Command Encoding:
 +   *  CharStrings commands are encoded in 1 or 2 bytes.
 +   *
 +   *  Single byte commands are encoded in 1 byte that contains a value between
 +   *  0 and 31 inclusive.
 +   *  If a command byte contains the value 12, then the value in the next byte
 +   *  indicates a command. This "escape" mechanism allows many extra commands
 +   * to be encoded and this encoding technique helps to minimize the length of
 +   * the charStrings.
