Be careful that system locales may not be here, though you may need the
locale information in Postgres. They may also be broken (which is in fact
often the case), so don't depend on them.

I can help for french, icelandic, and german and norwegian (though for the
two last ones, I guess there are more appropriate persons on this list :).

They all have, as soon as we take care of accents, which are all put at
the end with an english system. And of course, they are different for each
language :)

PS : I'm sorry, Tom, I haven't been able to work on the faq for the past
