Diacritic Sensitivity in UWP AutoComplete (SfTextBoxExt)

The control does not stick with one type of keyboard, so you can populate items from a language with letters containing diacritics, and search for them with English characters from an en-US keyboard. Users can enable or disable the diacritic sensitivity using the IgnoreDiacritic property. The following code example demonstrates how to enable the diacritic sensitivity. The items in the suggestion list will be populated by entering any diacritic character of that alphabet.
