ISO Language Codes - http :// www . loc . gov / standards / iso639 - 2 / php / code_list . php
Because the language codes specified by ISO 639 - 2 / T are three characters long , they must be packed to fit into a 16 - bit field .
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 .
