characters for example start at code position 0980
(0 000 1001 1000 0000), which is indicated by the coding ‘13’ in byte 3
(shown by the italicized underlined digits).
• Byte 4 indicates GSM Default Alphabet character ‘53’, e.g.. "S".
• Byte 5 indicates a UCS2 character offset to the base pointer of ‘15’,
expressed in binary as follows 001 0101, which, when added to the base
pointer value results in a sixteen bit value of 0000 1001 1001 0101, e.g..
‘0995’, which is the Bengali letter KA.
• Byte 8 contains the value ‘FF’: as the string length is 5, this a valid
character in the string, where the bit pattern 111 1111 is added to the
base pointer, yielding to a sixteen bit value of 0000 1001 1111 1111 for
the UCS2 character (that is ‘09FF’).
• Byte 9 contains the padding value OxFF.
3. If the first byte of the alpha string is set to ‘0x82’, then the 2 nd byte contains the
length of the string (number of characters).The 3 rd and 4 th bytes contain a 16 bit
number which defines the complete 16 bit base pointer to a "half-page" in the
UCS2 code space, for use with some or all of the remaining bytes in the string.
The 5 th and subsequent bytes in the string contain coding as follows:
• if bit 8 of the byte is set to zero, the remaining seven bits of the byte
contain a GSM Default Alphabet character,
• if bit 8 of the byte is set to one, the remaining seven bits are an offset
value added to the base pointer defined in bytes 3 and 4, and the resulting
16 bit value is a UCS2 code point, and defines a UCS2 character.
Example 3
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8 Byte 9
‘82’ ‘05’ ‘05’ ‘30’ ‘2D’ ‘82’ ‘D3’ ‘2D’ ‘31’
In the example above:
• Byte 2 indicates there are 5 characters in the string
• Bytes 3 and 4 contain a 16 bit base pointer number of ‘0530’, pointing to
the first character of the Armenian character set.
• Byte 5 contains a GSM Default Alphabet character of ‘2D’, which is a dash
"-".
• Byte 6 contains a value ‘82’, which indicates it is an offset of ‘02’ added to
the base pointer, resulting in a UCS2 character code of ‘0532’, which
represents Armenian character Capital BEN.
• Byte 7 contains a value ‘D3’, an offset of ‘53’, which when added to the
base pointer results in a UCS2 code point of ‘0583’, representing Armenian
Character small PIWR.
