You may be able to build your own sorting function using localeCompare() that - at least according to the MDC article on the topic - should sort things correctly.

If that doesn't work out, here is an interesting SO question where the OP employs string replacement to build a "brute-force" sorting mechanism.

Also in that question, the OP shows how to build a custom textExtract function for the jQuery tablesorter plugin that does locale-aware sorting - maybe also worth a look.

Edit: As a totally far-out idea - I have no idea whether this is feasible at all, especially because of performance concerns - if you are working with PHP/mySQL on the back-end anyway, I would like to mention the possibility of sending an Ajax query to a mySQL instance to have it sorted there. mySQL is great at sorting locale aware data, because you can force sorting operations into a specific collation using e.g. ORDER BY xyz COLLATE utf8_polish_ci, COLLATE utf8_german_ci.... those collations would take care of all sorting woes at once.
