        I don't suppose it is possible to use the Unicode
collation order when using unicode?

How does one get UTF-8 collation order?

I would think think that a character specific ordering specified
in LC_COLLATE would take precedence over a less specific regional ordering.

I.e LC_COLLATE="XXX.UTF-8" -- Seems like it should use the UTF-8 rules
over the XXX rules for COLLATION.  If they wanted regional rules,
then "XXX" alone without specifying an international standard like unicode,
would allow regional rules to take precedence.

But if they specify a specific character encoding for the characters,
under collation, why wouldn't the character set's collation order be used?

So how does one get UTF-8's Unicode collation ordering?
