Good app but I cannot type vietnamese

I like this app. Nice layout and colors. Easy to operate. Nothing to complain about the English-Vietnamese dictionary.
Problem is with the Vietnamese-English dictionary. I cannot type vietnamese, with accented characters, in the search box therefore the Vietnamese-English dictionary is not very useful. Hope that this problem will be fixed in the next update.
