"The first two letters of the code are the two letters of ISO 3166-1
alpha-2 country codes"

There are also issues in the way you divide numbers. In many
countries, number are organized by sequence of 3 digits. For example,
in Japan

10 yen = ju(10) yen
1000 yen = ichi(1) sen yen
but    10000 yen = ichi(1) man yen (and not ju sen yen)

10000   万　　　    man
1000   千　　　    sen

wa-on     kan-on    mandarin
1 一   hito       ichi     yi
2 二   futa       ni       ar, liang *
3 三   mi         san      san
4 四   yon        shi *    si
5 五   itsutsu    go       wu
6 六   mu         roku     liu
7 七   nana       shichi * qi
8 八   ya         hachi    ba
9 九   kokonotsu  kyuu     jiu
10 十   tou        jyuu     shi

And this is actually used in daily life, in case people think its a
corner case.
