Dataview Sorting

[Ste]

Hi all,
I've a problem sorting a DataView.
I've created a DataTable with only a string field, and written in it two
records with the valutes "a" (ascii code 97) and "~" (ascii code 126). Then
I've created a DataView that wraps the DataTable, and applied the Sort
method on this field.
The problem is that DataView puts the record with value "~" before "a"...I
think it uses a Latin charset table, instead the standard ascii...

Is there any way to sort the records in DataView with ascii order?
