Sort problem in dhtmlxGrid

 when I click the header of grid and Sort it,it doesn’t sort as I want.for example,it sort like this:

see                               Z398



peo                               peo



Z398        the right answer is:  Pea



Sea                               see 



Pea                               Sea 



 



it sort the Lowercase letters first,and Capital letters second.

By default sorting is case sensitive, you can change this behavior through custom sorting
