       * CharStrings are encoded following the the CharString Encoding sequence
       * describe in Chapter 6 of the "Adobe Type1 Font Format" specification.
       * The value in a byte indicates a command, a number, or subsequent bytes
       * that are to be interpreted in a special way.
       *
       * 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.
