* CharStrings are encoded following the the CharString Encoding sequence

*
* CharString Number Encoding:
- * A CharString octet containing the values from 32 through 255 inclusive
+ * 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 octet.
+ * 107 inclusive may be encoded in single byte.
*
- * 2. A CharString octet containing a value, v, between 247 and 250 inclusive,
- * indicates an integer involving the next octet, w, according to the formula:
+ * 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 octet containing a value, v, between 251 and 254 inclusive,
- * indicates an integer involving the next octet, w, according to the formula:
+ * 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:

*
* 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

* indicates a command. This "escape" mechanism allows many extra commands
* to be encoded and this encoding technique helps to minimize the length of
