sorting files alphabetically in Polish does not work properly

[lukand]

Would it be possible to improve Multi Commander so it would sort the files properly in Polish?

MC currently only support fast sort. That means that some characters in some languages does not sort correct.
There are plans in include a more correct language depended sort. However that require a bit redesigned and it will also be an option for it, because it is slower, and some other sort options might not work with it.
