Answer 1

You can use Intl.Collator or String.prototype.localeCompare, introduced by ECMAScript Internationalization API:

"Ł".localeCompare("Z", "pl");              // -1
new Intl.Collator("pl").compare("Ł","Z");  // -1

-1 means that Ł comes before Z, like you want.

Note it only works on latest browsers, though.
