Internationalization is an overconstrained problem which is impacted
and influenced by human politics, incuding from the Cold War and who
attended which internal standards bodies meetings. So much so that an
I18N expert (very knowledgable about the problems in this domain) has
been known to have said (in a bar, late at night, and after much
alcohol) that it would be simpler to teach the entire human race
English.
Unfortunately, that's not going to happen, and if we are going to deal
with the market of "everyone which doesn't speak English", we're going
to have to live with Unicode, warts at and all. Seriously speaking,
UTF-8 is the worst encoding, except for all of the others. :-)
