Dialog list_box items not sorted properly

Hi,

I've created dialog with list box control. After populating with some data, I get wrong alphabetical order of items.Specifically item with character "č" is added on the end of the list[1] When i change character "č" to some other latin charcter like "š" everything works like charm[2]. Can you recommend me some workaround.Thank you
