> It would be good for Derby to have built in Language based ordering based on locale specific
Collator.
> Language based ordering is an important feature for international deployment.  DERBY-533
offers one implementation option for this but according to the discussion in that issue National
Character Types carry a fair amount of baggage with them especially in the form of concerns
about conversion   to and from datetime and number types. Rick  mentioned SQL language for
collations as an option for language based ordering. There may be other options too, but I
thought it worthwhile to add an issue for the high level functional concern, so the best choice
can be made for implementation without assuming that National Character Types is the only
solution.
