- * 2) if the first octet in the alpha string is '81', then the

- * base pointer to a "half page" in the UCS2 code space, to be
- * used with some or all of the remaining octets in the string.
- * The fourth and subsequent octets contain codings as follows:
- * If bit 8 of the octet is set to zero, the remaining 7 bits
- * of the octet contain a GSM Default Alphabet character,
- * whereas if bit 8 of the octet is set to one, then the
- * remaining seven bits are an offset value added to the
- * 16 bit base pointer defined earlier...
- * 3) If the first octet of the alpha string is set to '82', then
- * the second octet contains a value indicating the number of
- * characters in the string, and the third and fourth octets
- * contain a 16 bit number which defines the complete 16 bit
