Duolingo asking for a diacritic that's not on the keyboard
I'm in the middle of the "Hobby" portion of the Duolingo Ukrainian course, and when it asks me for the word for literature, and I write "література", which seems to be correct, Duolingo says it's wrong and keeps asking me to type the word in again. I couldn't get out of the lesson until I copied the answer from Duolingo's correction alert and pasted it into the next screen that asked me for it.
The problem seems to be that in the "right" answer, the word is marked on one of the syllables to show stress, and it looks like this: літератýра. I can't find any way on the Ukrainian keyboard to put that accent mark over the "y", so I repeatedly get the answer "wrong", but I think I probably wrote it correctly in the first place.
