|
|
The packing algorithm must map each of the three characters, which are always lowercase, into a 5-bit integer and then concatenate
|
||
|
|
these integers into the least significant 15 bits of a 16-bit integer, leaving the 16-bit integer's most significant bit set to zero.
|
||
|
|
|
||
|
|
One algorithm for performing this packing is to treat each ISO character as a 16-bit integer. Subtract 0x60 from the first character
|
||
|
|
and multiply by 2^10 (0x400), subtract 0x60 from the second character and multiply by 2^5 (0x20), subtract 0x60 from the third character,
|
||
|
|
and add the three 16-bit values. This will result in a single 16-bit value with the three codes correctly packed into the 15 least
|
||
|
|
significant bits and the most significant bit set to zero.
