3.5.2 IRA character set
The character set used in SMS text mode is the IRA.
This set defines each char as a 7-bit value, hence from 0x00 to 0x7F. The table below reports all the
chars supported and their hexadecimal code. To obtain the code for a char in the table remember that
in the row it is reported the least significant nibble (4 bits) and in the column the most significant
nibble. The empty cells correspond to reserved combinations.

For example:
1- Let's assume you want to find the IRA code for the character '&':
From the table you find:
- most significant Nibble: 2
- least significant Nibble: 6
Hence the IRA code for the '&' character is the hexadecimal 0x26.
